Short Description:

Alloy thermal cutoff is a one time, non returnable device.It is widely used in over-temperature protection of electrical equipment. The utility model is mainly composed of a fusible alloy with low melting point, a flux, a plastic or ceramic shell, a sealing resin and a lead wire. Under normal operating conditions, the flammable alloy is connected to both leads, and the fusible alloy melts when the alloy thermal cutoff feels abnormal heat and reaches a predetermined fuse temperature, and in the role of the fuse under the fast contraction to the two ends of the lead, thus breaking the circuit.

Alloy thermal cutoff are axial type and radial type, rated action temperature: 76-230 °C, rated current: 1-200A, safety certification including: Rohs CCC,REACH and other environmental protection requirements
