Fuse definition, a tube, cord, or the like, filled or saturated with combustible matter, for igniting an explosive. Later those pads fuse with the anterior end of the centrum of the vertebra to which they belong; where the vertebral column is rendered inflexible, the disks are ossified with the centra and all trace of them is lost. a short fuse  Some installations use these Edison-base circuit breakers. These circular knobs can "blow" and cause power outages. 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. MultiUn. … The resistance of the element generates heat due to the current flow. 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. Definition of fuse noun from the Oxford Advanced Learner's Dictionary. Low-voltage high rupture capacity (HRC) fuses are used in the area of main distribution boards in low-voltage networks where there is a high prospective short circuit current. across it. 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. Fuses are the precursor to modern breakers. There is a direct relationship between a fuse's cold resistance and its voltage drop value. These devices are often used in aerospace/nuclear applications where replacement is difficult, or on a computer motherboard so that a shorted mouse or keyboard does not cause motherboard damage. These Edison base fuses would screw into a fuse socket similar to Edison-base incandescent lamps. Definition of FUSE in the Definitions.net dictionary. The operating time is not a fixed interval but decreases as the current increases. Other fuses have other indication methods including: Some fuses allow a special purpose micro switch or relay unit to be fixed to the fuse body. noun (Mil.) A circuit breaker at 115 kV may cost up to five times as much as a set of power fuses, so the resulting saving can be tens of thousands of dollars. Fuses The fuse breaks the circuit if a fault in an appliance causes too much current to flow. Meaning of FUSE. The associated high pressure (often greater than 100 atmospheres) and cooling gases rapidly quench the resulting arc. Oliver Hogg states the following about fuze: The word "fuze" is often spelt "fuse" by … Extra Examples . 40 synonyms of fuse from the Merriam-Webster Thesaurus, plus 48 related words, definitions, and antonyms. It contains a piece of wire... | Meaning, pronunciation, translations and examples See Fuze. Surface mount fuses have solder pads instead of leads. How to use fuse in a sentence. ), n. A tube, filled with combustible matter, for exploding a shell, etc. Such fuses can only be used outdoors. Fuses (may be found in place of circuit breakers) – rewirable fuses have a piece of special fuse wire running between two screws. Apart from protecting equipment, they are also used as safety measures to prevent any safety hazards to humans. In an explosive, pyrotechnic device, or military munition, a fuse (or fuze) is the part of the device that initiates function. What does electrical fuse mean? If your on some weird 10x server with screwed up loot tables that have fuses as very rare on them (yes there are servers like this). contents of the two cells fuse together, cytoplasm ~ B, Copyright © 2020 LoveToKnow. Electrical Fuse is a Protective Device that Interrupts Power Supply in case of Short Circuit. 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. FUZE: A device with explosive components designed to initiate a main charge. While in this state, the breaker is effectively useless: it does not provide any overcurrent protection.. The blown fuse cuts off the electricity to stop the lead and appliance from overheating and causing a fire. 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. 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. This term is normally used in short circuit conditions and the values are used to perform co-ordination studies in electrical networks. What does fuse mean? Fuses for high-voltage equipment, up to 115,000 volts, are rated by the total apparent power (megavolt-amperes, MVA) of the fault level on the circuit. Fuse definition is - to reduce to a liquid or plastic state by heat. A cable limiter is similar to a fuse but is intended only for protection of low voltage power cables. The fuse blew as he pressed the button to start the motor. The device is included with a metal strip where it gets dissolved when there is a flow of an extended range of current values. fuse /fjuːz/ Definitions. A mechanical or electrical mechanism used to detonate an explosive charge or device such as a bomb or grenade. Heres a look at the ins and outs of a fuse box: In electronics and electrical engineering, a fuse (from the French fusée, Italian fuso, "spindle" ) is a type of low resistance resistor that acts as a sacrificial device to provide overcurrent protection, of either the load or source circuit. en.wiktionary.org (also fuze in US) A cord that, when lit, conveys the fire to some explosive device. GAMES BROWSE THESAURUS WORD OF THE DAY WORDS AT PLAY. The PPTC thermistor is self-resetting in that when current is removed, the device will cool and revert to low resistance. Fuses for low voltage power circuits may have bolted blade or tag terminals which are secured by screws to a fuseholder. When the fuse element blows, the indicating pin extends to activate the micro switch or relay, which, in turn, triggers an event. For example, UL 248-19 allows photovoltaic fuses to be rated up to 1500 volts, DC, versus 1000 volts under the general requirements. International Electrotechnical Commission, polymeric positive temperature coefficient, edison.rutgers.edu/patents/ — U.S. Patent Office number 438305 "Fuse Block" (.pdf), http://lees.mit.edu/public/In_the_News/Electrical+Rebuilder's+Exchange.pdf, https://en.wikipedia.org/w/index.php?title=Fuse_(electrical)&oldid=1000285426, Articles with unsourced statements from February 2015, Wikipedia articles needing clarification from July 2020, Articles with unsourced statements from February 2019, Creative Commons Attribution-ShareAlike License, Melting of internal conductor due to heat generated by excessive current flow. However, any such breaker sold today does have one flaw. IEC standards refer to a "fuse" as the assembly of a fusible link and a fuse holder. They were traditionally used to protect electronic equipment and prevent fires, but have largely been replaced by circuit breakers. When you weld two pieces of metal together using a torch, this is an example of when you fuse. 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. A fuse rated for 1 A at 25 °C may conduct up to 10% or 20% more current at −40 °C and may open at 80% of its rated value at 100 °C. The breaking capacity is the maximum current that can safely be interrupted by the fuse. ... plural fuses. Fuses can be designed and manufactured to higher standards than the minimum standards required to pass U.L. One form of fuse box abuse was to put a penny in the socket, which defeated overcurrent protection and resulted in a dangerous condition. Silica sand or non-conducting liquids may be used. To unite as if by melting together; blend. Rated voltage should be higher than the maximum voltage source it would have to disconnect. External trip indicator — similar function to striker pin, but can be externally attached (using clips) to a compatible fuse. 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. Electrical fuses play the role of miniature circuit breakers. often fuze A mechanical or electrical mechanism used to detonate an explosive charge or device such as a bomb or grenade: "A mechanical ... switch is used to initiate the fuzes" (International Defense Review). Information and translations of FUSE in the most comprehensive dictionary definitions resource on … It may be installed in a circuit-breaker box with a door. IEC and UL nomenclature varies slightly. 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. [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. 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. The fuse is arranged in series to carry all the current passing through the protected circuit. Standards for automotive fuses are published by SAE International (formerly known as the Society of Automotive Engineers). Most fuses are marked on the body or end caps with markings that indicate their ratings. To join (different pieces or elements) together physically, as by melting or heating. Indicating pin or striker pin — extends out of the fuse cap when the element is blown. There are two styles of fuse base that can be screwed into these units: one designed for rewirable fusewire carriers and one designed for cartridge fuse carriers. Ratings were 5, 10, 15, 20, 25, and 30 amperes. The voltage drop should be taken into account, particularly when using a fuse in low-voltage applications. Define electrical fuse. National Electrical Code Medium-voltage fuses are also used to protect motors, capacitor banks and transformers and may be mounted in metal enclosed switchgear, or (rarely in new designs) on open switchboards. 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. See more. Fuse boxes are less common than breaker boxes, but still exist in some homes. When talking about being laid off, he has a short fuse. electrical fuse synonyms, electrical fuse pronunciation, electrical fuse translation, English dictionary definition of electrical fuse. Fuze Fuze (? This standard applies to fuses rated 1 kV or less, AC or DC, and with breaking capacity up to 200 kA.
