That part of a fuse which is designed to melt when the rated current is exceeded.
A circuit protection device consisting of a conductor surrounded by heat-resistant insulation. The conductor is smaller than the wire it protects, so it acts as the weakest link in the circuit. Unlike a blown fuse, a failed fusible link must frequently be cut from the wire for replacement.
Device installed local to the door or shutter which will fracture at a specified temperature to release a door closing mechanism. (This originates from prEN 14600 for fire doors)
Two metallic pieces that are joined together by low temperature alloy. When the ambient temperature exceeds that of the alloy the connection melts and the pieces separate. These are used to release holding chains or cables that maintain a mechanical fire door release system. The most common temperature for a fire door is 165 degree F.
A type of fuse consisting of short strands of wire held together by solder. Color coded outer layers identify the level of current at which they will "open". Fusible links may be located anywhere in a circuit.
a poor man's fuse, being nothing more than a short piece of rubber-insulated wire designed to melt open in the event of overcurrent, with no hard sheathing of any kind
a short section of wire three or four gauges smaller then the wire it's protecting
Soft, heat sensitive metal latch that holds a faucet or safety funnel open. In the event of a fire, the link melts, allowing the faucet or funnel to snap shut.
An electrical safety device normally located in a furnace that burns and opens the circuit during an overheat situation.
A piece of wire in a wiring harness that performs the same service as a fuse. If overloaded, the fusible link will melt and interrupt the circuit.
Wire designed to open a circuit by melting, when too much current flows through it.
A safety device consisting of a metal of low melting point inserted into a machine, boiler, or linkage that will melt if the temperature rises above a certain point thereby closing or shutting off the appliance.
A connecting link device that fuses or melts when exposed to heat. Used in sprinkler heads, fire doors, and ventilators. A piece of material (usually low melting point metals) designed to fail in a fire or under stress to activate a safety device such as a fire door.
A fusible link is a device consisting of two strips of metal soldered together with a fusible alloy that is designed to melt at a specific temperature, thus allowing the two pieces to separate.
