The thermal fuses/cutoffs are widely used for security to prevent damage of device due to the rise in the ambient temperature. Transmission of heat to the thermal pellet due to the rise in the ambit dangerous(opening temperature), causes melting of the thermal pellet, cutting off and opening the contact of Lead Wire A and Electrode by means of extending Spring-S type and pushing electrode away. It can't be recovered after functioning even if the temperature is reduced. Thermal Fuses are used for as follows:

1. Heating appliance-Electric heater, Electric iron, Electric stove, Electric blanket, Hair dryer, etc.

2. Motor-Air conditioner, Duplicator, Exhaust fan, Electric fan, Electric washing machines, Compressor, Every kinds of motors, etc.
