To blend two or more substances by melting. As nouns the difference between fuze and fuse is that fuze is an alternative spelling of fuse in the sense of a detonator while fuse is (also'' fuze ''in us ) a cord that, when lit, conveys the fire to some explosive device. Fuses for low voltage power circuits may have bolted blade or tag terminals which are secured by screws to a fuseholder. This is not the case with fuses, which rely on melting processes where no mechanical operation is required for the fuse to operate under fault conditions. What does FUSE mean? Blade type. Fuse definition. 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. Once this device has functioned in an open circuit, it ought to rewire or changed based on the type of fuse. In medium-voltage distribution systems, a power fuse may be used to protect a transformer serving 1–3 houses. 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. 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. If so, if the door is closed, the door may hold down the breaker's reset button. Find more ways to say fuse, along with related words, antonyms and example phrases at Thesaurus.com, the world's most trusted free thesaurus. Chances are that server has a currency and a shop. Circuit breaker fuses are designed as permanent replacements for Type T fuses; there are no Type S circuit breaker fuses. The energy is mainly dependent on current and time for fuses as well as the available fault level and system voltage. jump to other results. It contains a piece of wire which melts when there is a fault so that the flow of electricity stops. Fuse markings[9] will generally convey the following information, either explicitly as text, or else implicit with the approval agency marking for a particular type: Fuses come in a vast array of sizes and styles to serve in many applications, manufactured in standardised package layouts to make them easily interchangeable. If you are asked for a cartridge safety switch, it refers to a 60 or 30amp switch. Synonym Discussion of fuse. 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. The I2t rating is related to the amount of energy let through by the fuse element when it clears the electrical fault. 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. Meaning of electrical fuse. Normal fast-blow fuses are the most general purpose fuses. Electrical Fuse The fuse is a device used in an electrical circuit for protecting electrical devices against overloads and short circuit. Martha quickly explained, leaving Quinn's short fuse unlit. contents of the two cells fuse together, cytoplasm ~ B, Copyright © 2020 LoveToKnow. 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. [16]. What does fuse mean? Fuse wire was never used in North America for this reason, although renewable fuses continue to be made for distribution boards. Swe-Check: The Circuit Protection Specialists. 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. electrical fuse - an electrical device that can interrupt the flow of electrical current when it is overloaded. Inside the fuse is a metal strip that is connected to both metal ends of the fuse body. Electric fuze synonyms, Electric fuze pronunciation, Electric fuze translation, English dictionary definition of Electric fuze. 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. Thermal fuses are a 'one shot', non-resettable device which must be replaced once they have been activated (blown). The little string sticking out of a bomb that you light in order to get the bomb to go off is an example of a fuse. It contains a piece of wire... | Meaning, pronunciation, translations and examples [13][14] Some installations use these Edison-base circuit breakers. The element must not be damaged by minor harmless surges of current, and must not oxidize or change its behavior after possibly years of service. This standard applies to fuses rated 1 kV or less, AC or DC, and with breaking capacity up to 200 kA. Connecting fuses in series does not increase the rated voltage of the combination, nor of any one fuse. However, any such breaker sold today does have one flaw. 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. Fuses for commercial or industrial power systems must have higher interrupting ratings, with some low-voltage current-limiting high interrupting fuses rated for 300,000 amperes. July 16, 2018 Comments Off on Fuse definition News Like. 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. 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). It is a sacrificial device; once a fuse has operated it is an open circuit, and must be replaced or rewired, depending on its type. Definition of FUSE in the Definitions.net dictionary. Such fuses can only be used outdoors. Definition of electrical fuse in the Definitions.net dictionary. National Electrical Code The fuse element may be surrounded by air, or by materials intended to speed the quenching of the arc. Definitions of electrical fuse, synonyms, antonyms, derivatives of electrical fuse, analogical dictionary of electrical fuse (English) ... fuse, fusee, fuze, fuzee, primer, priming - electrical fuse, fuse, safety fuse [Dérivé] deactivate, defuse [Ant.] A miniature time-delay 250 V fuse that will interrupt a 0.3 A current at after 100 s, or a 15 A current in 0.1 s. 32 mm (1 1/4") long. 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 breaks the circuit if a fault in an appliance causes too much current to flow. Some vehicles use a dual 12/42 V DC electrical system[10] that will require a fuse rated at 58 V DC. ‘Electrical systems still using fuses may work just fine.’ ‘For spare carry a set of drive belts, hose pipes, loose electrical wire, insulation tape, extra fuses and coolant’ ‘The electromagnetic pulse generated by the test led to power surges in electrical cables in Hawaii, blowing fuses… A thermal fuse is often found in consumer equipment such as coffee makers, hair dryers or transformers powering small consumer electronics devices. Fuse definition, a tube, cord, or the like, filled or saturated with combustible matter, for igniting an explosive. fuse /fjuːz/ Definitions. circuit breaker, breaker - a device that trips like a switch and opens the circuit when overloaded. Find another word for fuse. Electrical Fuse is although an old protective device but still in use due to its high operating time. Electrical fuses play the role of miniature circuit breakers. They contain a fusible, temperature-sensitive composition which holds a spring contact mechanism normally closed. The device is included with a metal strip where it gets dissolved when there is a flow of an extended range of current values. a short fuse Fuses are designed to have particular characteristics of operating time compared to current. In North American standards, the fuse is the replaceable portion of the assembly, and a fuse link would be a bare metal element for installation in a fuse. Expulsion fuses are defined as follows: Expulsion fuse. Swe-Check sells fuses and circuit protection products. Definition of FUSE in the Definitions.net dictionary. See fuze. 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). Voltage drop often is not significant in more traditional wire type fuses, but can be significant in other technologies such as resettable (PPTC) type fuses. Fuse is the less expensive, effective, simple and high degree of safety device in circuit protection. This term is normally used in short circuit conditions and the values are used to perform co-ordination studies in electrical networks. The voltage drop should be taken into account, particularly when using a fuse in low-voltage applications. They are generally rated for circuits no higher than 32 volts direct current, but some types are rated for 42-volt electrical systems. Fuses are the precursor to modern breakers. See Fuze. Automotive fuses are a class of fuses used to protect the wiring and electrical equipment for vehicles. 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. Indicating pin or striker pin — extends out of the fuse cap when the element is blown. fuse noun /fjuːz/ /fjuːz/ Idioms. Their function is to provide protection of discrete components, or of complete circuits, by reliably melting under current overload conditions. If there is a short or fault anywhere in the circuit, or the circuit is overloaded, the metal strip, or link, heats up and quickly melts, opening the circuit and shutting off the power. The PPTC thermistor is self-resetting in that when current is removed, the device will cool and revert to low resistance. High rupturing capacity fuses can be rated to safely interrupt up to 300,000 amperes at 600 V AC. cartridge fuse - a fuse cased in a tube. (Fuse wire is commonly supplied to consumers as short lengths of 5A-, 15A- and 30A-rated wire wound on a piece of cardboard.) 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. [citation needed]. The melting I2t is proportional to the amount of energy required to begin melting the fuse element. en.wiktionary.org. 40 synonyms of fuse from the Merriam-Webster Thesaurus, plus 48 related words, definitions, and antonyms. Fuse. Fuses are used on power systems up to 115,000 volts AC. Fuse definition, a tube, cord, or the like, filled or saturated with combustible matter, for igniting an explosive. Fuse is defined as to join together to form one, especially when joined by intense heat. The fuse in a plug is a safety device designed to protect the lead rather than the appliance. This should be higher than the prospective short-circuit current. Medium-voltage fuses may have liquid-filled envelopes to assist in the extinguishing of the arc. Plasma inside the glass tube may continue to conduct current until the current diminishes to the point where the plasma becomes a non-conducting gas. Various kinds of proximity fuzes are designed for various targets such as planes, missiles, ships at sea and ground forces. Cartridge (ferrule) fuses have a cylindrical body terminated with metal end caps. To unite as if by melting together; blend. 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). Such tampering will not be visible without full inspection of the fuse. Some cartridge fuses are manufactured with end caps of different sizes to prevent accidental insertion of the wrong fuse rating in a holder, giving them a bottle shape. In the field of electronics or electrical, a fuse is considered as the most crucial device which is employed in various electrical circuits that give protection from the overcurrent conditions. Pole-mounted distribution transformers are nearly always protected by a fusible cutout, which can have the fuse element replaced using live-line maintenance tools. The manufacturer may specify the voltage drop across the fuse at rated current. Swe-Check sells fuses and circuit protection products. 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). Surface-mount technology "chip type" fuses feature few or no markings, making identification very difficult. UL 248 currently has 19 "parts".

Fuses for small, low-voltage, usually residential, wiring systems are commonly rated, in North American practice, to interrupt 10,000 amperes. 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). Some blade-type terminals are held by spring clips. Over the years MCBs have been made for both styles of base. 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. Some types of circuit breakers must be maintained on a regular basis to ensure their mechanical operation during an interruption. Electrical power and choosing fuses. Filling a fuse body with sand provides additional cooling of the arc and increases the breaking capacity of the fuse. In an explosive, pyrotechnic device, or military munition, a fuse (or fuze) is the part of the device that initiates function. noun (Mil.) Circuit Breaker Fuses . Some types of distribution switchgear use fuse links immersed in the oil that fills the equipment. We use cookies and similar technologies to provide website functionality and traffic analysis. 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. 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. GAMES BROWSE THESAURUS WORD OF THE DAY WORDS AT PLAY. See more. 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). Some automotive fuses are occasionally used in non-automotive electrical applications. Fuses consist of a low-resistance metal or wire that is used to close a circuit. If you have additional comments or suggestions, please contact us at belcoelectric@gmail.com or call us directly at 305-801-9293. fuse /fjuːz/ Definitions. For example, bottle style fuses distinguish between ratings with different cap diameters. Learn what these markings mean. All fuses, including cartridge fuses, are the "weak link" in an electrical circuit. In large fuses, current may be divided between multiple strips of metal. Fuses designed for soldering to a printed circuit board have radial or axial wire leads. 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. 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). Synonyms: associate, coalesce, combine… Antonyms: break up, dissever, part… Find the right word. Automotive fuses can be mounted in fuse blocks, inline fuse holders, or fuse clips. When a fault or overload current flows through the fuse wire, it will become hot and melt. Fuses. Electrical fuses play the role of miniature circuit breakers. It is a deliberate weak link in a circuit which will 'blow' if an electrical appliance or extension lead draws too much current due to either an overload or a fault. In electronics and electrical engineering a fuse (from the Latin “fusus” meaning to melt) is a type of sacrificial overcurrent protection device. … When you weld two pieces of metal together using a torch, this is an example of when you fuse. Similar appearing fuses may have significantly different properties, identified by their markings. The fuses to be considered are current sensitive devices designed to serve as the intentional weak link in the electrical circuit. All Rights Reserved. Fuses have the advantages of often being less costly and simpler than a circuit breaker for similar ratings. Automotive glass fuses were made in different lengths, to prevent high-rated fuses being installed in a circuit intended for a lower rating. The general requirements (248-1) apply except as modified by the supplemental part (240-x). Semi-enclosed fuses are fuse wire carriers in which the fusible wire itself can be replaced. 248. This means that fuses can only be replaced by the preset (Type S) fuse rating. To become physically joined together, as by melting. 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. See more. Another word for fuse. Fuses only sense overcurrent, or to a degree, over-temperature, and cannot usually be used independently with protective relaying to provide more advanced protective functions, for example, ground fault detection. In electronics and electrical engineering, a fuse (from the French fusée, Italian fuso, "spindle" [1]) is a type of low resistance resistor that acts as a sacrificial device to provide overcurrent protection, of either the load or source circuit. The current-time characteristic of a fuse cannot always be correlated with that of the protective device. They are generally larger than screw-type fuses, and have ferrule cap or blade contacts. 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). To melt something, such as metal or glass, by heating. 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.
