Thermal fuses, defined as non-resettable, are single action devices that are widely used for the electrical equipments against over temperature. The thermal cutoffs are composed of the fusible alloy with low melting point and special resin, encapsulated in a plastic or ceramic housing. Under normal operated, the fusible alloy is joined by the two lead wires within the housing. When the thermal cutoff senses an abnormal heat and reach a preset temperature, the fusible alloy melts and disconnects the circuit completely with the aid of the special resin. Both Axial and Radial shapes are available, with rated current from 1A to 200A, Function temperature 76℃~221℃, certificated including UL, cUL, VDE,TUV,PSE, KTL, CCC and RoHS, REACH Compliant.
