A fuse is an automatic means of removing power from a faulty system; often abbreviated to ADS (Automatic Disconnection of Supply). A cartridge fuse found in amperage sizes 60amp or lower. Some automotive fuses are occasionally used in non-automotive electrical applications. There are several different types of automotive fuses and their usage is dependent upon the specific application, voltage, and current demands of the electrical circuit. Operating values will vary with each fuse family and are provided in manufacturer data sheets. The melted fuse breaks the circuit, disconnecting the faulty circuit and keeping you safe. en.wiktionary.org (also fuze in US) A cord that, when lit, conveys the fire to some explosive device. In electronics and electrical engineering a fuse (from the Latin “fusus” meaning to melt) is a type of sacrificial overcurrent protection device. How to use fuse in a sentence. In the UK, older electrical consumer units (also called fuse boxes) are fitted either with semi-enclosed (rewirable) fuses (BS 3036) or cartridge fuses (BS 1361). These types of fuse are used on equipment such as motors, which can draw larger than normal currents for up to several seconds while coming up to speed. Semi-enclosed fuses are fuse wire carriers in which the fusible wire itself can be replaced. Large power fuses use fusible elements made of silver, copper or tin to provide stable and predictable performance. Fuses are the precursor to modern breakers. Modern consumer units usually contain miniature circuit breakers (MCBs) instead of fuses, though cartridge fuses are sometimes still used, as in some applications MCBs are prone to nuisance tripping. The fuse is arranged in series to carry all the current passing through the protected circuit. The fuse wire in an electrical fuse is selected in such a way that it does not face any damage when the normally stipulated amount of current flows through the circuit. It may be installed in a circuit-breaker box with a door. When the surrounding temperature gets too high, the composition melts and allows the spring contact mechanism to break the circuit. Automotive fuses can be classified into four distinct categories: Most automotive fuses rated at 32 volts are used on circuits rated 24 volts DC and below. Find another word for fuse.  The fuse ideally would carry its rated current indefinitely, and melt quickly on a small excess. Why Use a Fuse? Apart from protecting equipment, they are also used as safety measures to prevent any safety hazards to humans. Meaning of FUSE. contents of the two cells fuse together, cytoplasm ~ B, Copyright © 2020 LoveToKnow. a short fuse The current-time characteristic of a fuse cannot always be correlated with that of the protective device. The exact fusing current is not as well controlled as an enclosed fuse, and it is extremely important to use the correct diameter and material when replacing the fuse wire, and for these reasons these fuses are slowly falling from favour. This article, we discuss Electrical Fuse, Types of Fuses, Construction, Operation, Working and … a mechanism in a bomb, torpedo, rocket, or artillery shell, usually having an easily detonated explosive charge and activated by the shock of impact, which detonates the main explosive charge. Cartridge (ferrule) fuses have a cylindrical body terminated with metal end caps. Another word for fuse. These type of fuses may have an impact pin to operate a switch mechanism, so that all three phases are interrupted if any one fuse blows. Synonyms: associate, coalesce, combine… Antonyms: break up, dissever, part… Find the right word. The PPTC thermistor is self-resetting in that when current is removed, the device will cool and revert to low resistance. Circuit breakers can be used as an alternative to fuses, but have significantly different characteristics. SAVED … Electrical Fuse is a Protective Device that Interrupts Power Supply in case of Short Circuit. This page was last edited on 14 January 2021, at 13:58. In the 1950s, fuses in new residential or industrial construction for branch circuit protection were superseded by low voltage circuit breakers. They are occasionally used in non-automotive electrical products. To become physically joined together, as by melting. Normal fast-blow fuses are the most general purpose fuses. (Fuse wire is commonly supplied to consumers as short lengths of 5 A-, 15 A- and 30 A-rated wire wound on a piece of cardboard.) Another word for fuse. The design does not allow for fitting of RCDs or RCBOs. Most fuses feature some kind of markings on the caps or label. Indicating pin or striker pin — extends out of the fuse cap when the element is blown. Some manufacturers of medium-voltage distribution fuses combine the overcurrent protection characteristics of the fusible element with the flexibility of relay protection by adding a pyrotechnic device to the fuse operated by external protective relays. Definition of electrical fuse in the Definitions.net dictionary. LOG IN; REGISTER; settings. Meaning of electrical fuse. Pole-mounted distribution transformers are nearly always protected by a fusible cutout, which can have the fuse element replaced using live-line maintenance tools. See Fuze. HRC fuses are widely used in industrial installations and are also used in the public power grid, e.g. To join (different pieces or elements) together physically, as by melting or heating. ), n. A tube, filled with combustible matter, for exploding a shell, etc. Such tampering will not be visible without full inspection of the fuse. Fuses (may be found in place of circuit breakers) – rewirable fuses have a piece of special fuse wire running between two screws. Fuse is the less expensive, effective, simple and high degree of safety device in circuit protection. Fuses consist of a low-resistance metal or wire that is used to close a circuit. en.wiktionary.org (also fuze in US) A cord that, when lit, conveys the fire to some explosive device. jump to other results. A dual-element fuse may contain a metal strip that melts instantly on a short circuit, and also contain a low-melting solder joint that responds to long-term overload of low values compared to a short circuit. Glass cartridge and plug fuses allow direct inspection of the fusible element. The fuse element is made of zinc, copper, silver, aluminum, or alloys among these or other various metals to provide stable and predictable characteristics. Phone: +61 3 9521 6133 Fax: +61 3 9521 6177 Web: www.swe-check.com.au . The energy is mainly dependent on current and time for fuses as well as the available fault level and system voltage. If you have a fuse box, it means your electrical service is quite old and likely is insufficient for the power demands of a modern home. It comprises a strip or a metal wire that dissolves when the heavy flow of current supplies through it. Automotive fuses can be mounted in fuse blocks, inline fuse holders, or fuse clips. Medium-voltage fuses rated for a few thousand volts are never used on low voltage circuits, because of their cost and because they cannot properly clear the circuit when operating at very low voltages.. Fuses are always connected in series with the component(s) to be protected from overcurrent, so that when the fuse blows (opens) it will open the entire circuit and stop current through the component(s). to change a fuse; Check whether a fuse has blown. This means that fuses can only be replaced by the preset (Type S) fuse rating. Wiring regulations usually define a maximum fuse current rating for particular circuits. a fuze which is ignited by heat or a spark produced by an electric current. In an explosive, pyrotechnic device, or military munition, a fuse (or fuze) is the part of the device that initiates function.In common usage, the word fuse is used indiscriminately. Fuse selection depends on the load's characteristics. The frequency of the AC fuses … In large fuses, current may be divided between multiple strips of metal. Fuses are widely used for protection of electric motor circuits; for small overloads, the motor protection circuit will open the controlling contactor automatically, and the fuse will only operate for short circuits or extreme overload. The IEC standard unifies several national standards, thereby improving the interchangeability of fuses in international trade. Learn what these markings mean. High-power fuse means that these fuses can interrupt several kiloamperes. A cord of readily combustible material that is lighted at one end to carry a flame along its length to detonate an explosive at the other end. Some blade-type terminals are held by spring clips. In medium-voltage distribution systems, a power fuse may be used to protect a transformer serving 1–3 houses. When the fuse blows, heat from the arc causes the boric acid to evolve large volumes of gases. Current-limiting fuses operate so quickly that they limit the total "let-through" energy that passes into the circuit, helping to protect downstream equipment from damage. This term is normally used in short circuit conditions and the values are used to perform co-ordination studies in electrical networks. Noun 1. electrical fuse - an electrical device that can interrupt the flow of electrical current when it is overloaded fuse, safety fuse cartridge fuse - a... Electrical fuse - definition of electrical fuse by The Free Dictionary. For example, bottle style fuses distinguish between ratings with different cap diameters. Rated voltage should be higher than the maximum voltage source it would have to disconnect. Element window — a small window built into the fuse body to provide visual indication of a blown element. A narrow tube filled with combustible material, or a wick saturated with such material, for setting off an explosive charge. The standard ampere ratings for fuses (and circuit breakers) in USA/Canada are considered 15, 20, 25, 30, 35, 40, 45, 50, 60, 70, 80, 90, 100, 110, 125, 150, 175, 200, 225, 250, 300, 350, 400, 450, 500, 600, 700, 800, 1000, 1200, 1600, 2000, 2500, 3000, 4000, 5000, and 6000 amperes. (The spelling FUSE may also be met for this term, but FUZE is the preferred spelling in this context.) See more. See more. The characteristics of the limiter are matched to the size of cable so that the limiter clears a fault before the cable insulation is damaged. They contain a fusible, temperature-sensitive composition which holds a spring contact mechanism normally closed. Renewable fuses have replaceable fuse elements, allowing the fuse body and terminals to be reused if not damaged after a fuse operation. Fuses are designed to have particular characteristics of operating time compared to current. Fuse is defined as to join together to form one, especially when joined by intense heat. Swe-Check sells fuses and circuit protection products. The device can be used to prevent a fire in a hair dryer for example, by cutting off the power supply to the heater elements when the air flow is interrupted (e.g., the blower motor stops or the air intake becomes accidentally blocked). Extra Examples . en.wiktionary.org (manufacturing, mining, military) The mechanism that ignites the charge in an explosive device. In the UK, older electrical consumer units (also called fuse boxes) are fitted either with semi-enclosed (rewirable) fuses (BS 3036) or cartridge fuses (BS 1361). Special current-limiting fuses are applied ahead of some molded-case breakers to protect the breakers in low-voltage power circuits with high short-circuit levels. Fuse wire was never used in North America for this reason, although renewable fuses continue to be made for distribution boards. The associated high pressure (often greater than 100 atmospheres) and cooling gases rapidly quench the resulting arc. If so, if the door is closed, the door may hold down the breaker's reset button. The terms are often interchanged. So-called self-resetting fuses use a thermoplastic conductive element known as a polymeric positive temperature coefficient (PPTC) thermistor that impedes the circuit during an overcurrent condition (by increasing device resistance). Where several fuses are connected in series at the various levels of a power distribution system, it is desirable to blow (clear) only the fuse (or other overcurrent device) electrically closest to the fault. The manufacturer may specify the voltage drop across the fuse at rated current. For all of the reasons above, Edison Fuses Inc. manufactures fuses not only to meet industry standards, but also to reach the highest quality standards found in the industry. The definition of a fuse is an electrical safety device that can stop current from flowing if it becomes overloaded, or a device that is used to ignite an explosive device. All fuses, including cartridge fuses, are the "weak link" in an electrical circuit. See more. There are many types of fuses, but the function of all these fuses is the same. , In North America, fuses were used in buildings wired before 1960. Meaning of electrical fuse. Some vehicles use a dual 12/42 V DC electrical system that will require a fuse rated at 58 V DC. that flows through it and the potential difference. What does electrical fuse mean? Fuse boxes are found in old Eastern CT homes. Automotive fuses are used to protect the wiring and electrical equipment for vehicles. Fuses contain a length of thin wire (usually of a metal alloy) that melts and breaks the circuit if too much current flows through it. Some fuses for medium-voltage applications use two or three separate barrels and two or three fuse elements in parallel. A standard fuse may require twice its rated current to open in one second, a fast-blow fuse may require twice its rated current to blow in 0.1 seconds, and a slow-blow fuse may require twice its rated current for tens of seconds to blow. Electrical Fuse is although an old protective device but still in use due to its high operating time. A fuse is an automatic disconnection of supply which is frequently shortened to … Standards for automotive fuses are published by SAE International (formerly known as the Society of Automotive Engineers). Existing Edison fuse boards can easily be converted to only accept Rejection Base (Type S) fuses, by screwing-in a tamper-proof adapter. UL 248-1 sets the general requirements for fuses, while the latter parts are dedicated to specific fuses sizes (ex: 248-8 for Class J, 248-10 for Class L), or for categories of fuses with unique properties (ex: 248-13 for semiconductor fuses, 248-19 for photovoltaic fuses). Something of an oddity, a circuit-breaker fuse screws into an Edison socket on the fuse panel, but rather than having a metal-alloy filament, this fuse has a mechanism that can be reset by pushing a small button on the face of the fuse. Swe-Check: The Circuit Protection Specialists. For example, fuse holders for North American class RK fuses have a pin that prevents installation of similar-appearing class H fuses, which have a much lower breaking capacity and a solid blade terminal that lacks the slot of the RK type. In this way, only the faulty circuit is interrupted with minimal disturbance to other circuits fed by a common supplying fuse. Most fuses are marked on the body or end caps with markings that indicate their ratings. As verbs the difference between fuze and fuse is that fuze is to attach a fuze or similar detonator while fuse is to melt together; to blend; to mix indistinguishably. If you are asked for a cartridge safety switch, it refers to a 60 or 30amp switch. What does electrical fuse mean? Ratings were 5, 10, 15, 20, 25, and 30 amperes. Definition of fuse written for English Language Learners from the Merriam-Webster Learner's Dictionary with audio pronunciations, usage examples, and count/noncount noun labels. Some fuses are designated high rupture capacity (HRC) or high breaking capacity (HBC) and are usually filled with sand or a similar material.. A proximity fuze is a fuze that detonates an explosive device automatically when the distance to the target becomes smaller than a predetermined value, or when the fuze and the target pass by each other. Medium-voltage fuses may have liquid-filled envelopes to assist in the extinguishing of the arc. Fuze Fuze (? chose en plomb (fr) [ClasseParExt.] SINCE 1828. A fuse is an electrical safety device built around a conductive strip that is designed to melt and separate in the event of excessive current. A fuse consists of a metal strip or wire fuse element, of small cross-section compared to the circuit conductors, mounted between a pair of electrical terminals, and (usually) enclosed by a non-combustible housing. A time-delay fuse (also known as an anti-surge or slow-blow fuse) is designed to allow a current which is above the rated value of the fuse to flow for a short period of time without the fuse blowing. The resistance of the element generates heat due to the current flow. Cartridge fuse carriers are also now available for DIN-rail enclosures.

High voltage expulsion fuses surround the fusible link with gas-evolving substances, such as boric acid. fuse /fjuːz/ Definitions. The voltage drop should be taken into account, particularly when using a fuse in low-voltage applications. If too high a current flows, the element rises to a higher temperature and either directly melts, or else melts a soldered joint within the fuse, opening the circuit. Fuses for low voltage power circuits may have bolted blade or tag terminals which are secured by screws to a fuseholder. In a multi-phase power circuit, if only one fuse opens, the remaining phases will have higher than normal currents, and unbalanced voltages, with possible damage to motors. Fuse packages may include a rejection feature such as a pin, slot, or tab, which prevents interchange of otherwise similar appearing fuses. These fuses are intended for installations following Canadian Electrical Code, Part I (CEC), or the National Electrical Code, NFPA 70 (NEC). Its essential component is a metal wire or strip that melts when too much current flows, which interrupts the circuit in which it is connected. IEC standards refer to a "fuse" as the assembly of a fusible link and a fuse holder. While in this state, the breaker is effectively useless: it does not provide any overcurrent protection.. The family of # articles includes igniters, cartridges, both explosive and shaped charges, cutters, detonators, fireworks, flares, fuse, fuzes, grenades, igniters, primers, release devices and signals of all types. High rupture capacity fuses may be rated to interrupt current of 120 kA. On the other hand, replacing a fuse without isolating the circuit first (most building wiring designs do not provide individual isolation switches for each fuse) can be dangerous in itself, particularly if the fault is a short circuit. A thermal fuse is often found in consumer equipment such as coffee makers, hair dryers or transformers powering small consumer electronics devices. in transformer stations, main distribution boards, or in building junction boxes and as meter fuses. Renewable fuses (rewirable or cartridge) allow user replacement, but this can be hazardous as it is easy to put a higher-rated or double fuse element (link or wire) into the holder (overfusing), or simply fitting it with copper wire or even a totally different type of conducting object (coins, hairpins, paper clips, nails, etc.) AC Fuse : The AC fuses are classified into 2 varieties they’re the low voltage fuses and therefore the high voltage fuses. electrical fuse synonyms, electrical fuse pronunciation, electrical fuse translation, English dictionary definition of electrical fuse.

The time and current operating characteristics of fuses are chosen to provide adequate protection without needless interruption. Once this device has functioned in an open circuit, it ought to rewire or changed based on the type of fuse. Synonym Discussion of fuse. The blown fuse must be replaced with a new device which is less convenient than simply resetting a breaker and therefore likely to discourage people from ignoring faults. Some fuses may have timing mechanisms, delaying the explosion for a short time, or up to several days after impact. fuse fuze in English translation and definition "fuse fuze", Dictionary English-English online. For example, UL 248-19 allows photovoltaic fuses to be rated up to 1500 volts, DC, versus 1000 volts under the general requirements. Fuses have been used as essential safety devices from the early days of electrical engineering. Some varieties of HRC fuse include special handling features. Fuse definition, a tube, cord, or the like, filled or saturated with combustible matter, for igniting an explosive.

Additional standard ampere ratings for fuses are 1, 3, 6, 10, and 601. A safety device that protects an electric circuit from becoming overloaded. Ambient temperature will change a fuse's operational parameters. Fuses are sacrificial devices used to protect much more expensive electrical components from the damaging effects of overcurrent. Semiconductor devices may use a fast or ultrafast fuse as semiconductor devices heat rapidly when excess current flows. Define electrical fuse. It is not intended to provide overload protection, but instead protects a cable that is exposed to a short circuit. Surface mount fuses have solder pads instead of leads. The power of an electrical appliance can be calculated from the current. [clarification needed] Once current is applied, resistance and voltage drop of a fuse will constantly grow with the rise of its operating temperature until the fuse finally reaches thermal equilibrium. However, any such breaker sold today does have one flaw. I2t parameters are provided by charts in manufacturer data sheets for each fuse family. Where the fuses in a system are of similar types, simple rule-of-thumb ratios between ratings of the fuse closest to the load and the next fuse towards the source can be used. The high temperature necessary to fuse cement clinker makes this process difficult to accomplish commercially, but it has many inherent merits and may be the process of the future, displacing the rotatory method. Its essential component is a metal wire or strip that melts when too much current flows through it, thereby stopping or interrupting the current. noun the hole in a shell prepared for the reception of the fuse. Fuses and circuit breakers. What does FUSE mean? Ceramic fuses have the advantage of a higher breaking capacity, facilitating their use in circuits with higher current and voltage. The fuse element may be surrounded by air, or by materials intended to speed the quenching of the arc. Electrical fuses play the role of miniature circuit breakers. High-voltage fuses of the expulsion type have fiber or glass-reinforced plastic tubes and an open end, and can have the fuse element replaced. The speed at which a fuse blows depends on how much current flows through it and the material of which the fuse is made.Manufacturers can provide a plot of current vs time, often plotted on logarithmic scales, to characterize the device and to allow comparison with the characteristics of protective devices upstream and downstream of the fuse. , Edison base (left) and Type S fuses (right), An older fuse box of the type used in North America, Some companies manufacture resettable miniature thermal circuit breakers, which screw into a fuse socket. Fuse definition is - to reduce to a liquid or plastic state by heat. The operating time is not a fixed interval but decreases as the current increases. When you overload the circuit in your house by turning on too many different appliances at once and your power to the appliances you are using shuts off, the electrical device that tripped and caused the power to stop to the overloaded circuit is an example of a fuse. High-voltage fuses are used to protect instrument transformers used for electricity metering, or for small power transformers where the expense of a circuit breaker is not warranted. It is used, for example, in networks where multiple cables may be used in parallel. Electric fuse was invented by Thomas Alva Edison in 1890. Electrical power and choosing fuses.
