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.

Rated functioning temperature(Tf):

The temperature at which a Thermal Fuse changes its state of conductivity to open circuit detection curret.The tolerance according to IEC60691 is from +0 to-10℃.(With Japan Electrical Appliance and Material Law,on the other hand,they must function in the tolerance range of ±7℃.).

Fusing(cut)-off temperature:

The fusing-off temperature indicates value measured in silicon oil with a temperature increased by 0.5-1℃ per minute and a detective current 10mA or less.

Holding temperature(Th):

The maximum temperature at which a thermal Fuse will not cause a change in state of conductivity to open circuit while conducting rated current for 168 hours. This rating is required by safety standards based on IEC60691.

Maximum temperature limit(Tm):

The maximum temperature at which a Thermal Fuse can be maimtained for 10 minutes without reclosing.This rating is requirde by safety standards based on IEC60691.

Rated current(Ir):

The allowable maximum current which a Thermal Fuse is able to carry.

Rated current(Ur):

The allowable maximum voltage which a Thermal Fuse is able to be applied.
