Specifications:
Tb series type heat protector is composed by bi-metal disc with movable contact, upper terminal, lower terminal with stationary contact, fixing base, insulating base, and lead wires. The fully enclosed structure can prevent the protector from dust or impurity pollution, the infiltration of lacquer and the damage caused by external force. When a metal case is used, it is covered with an insulating tube. When the current goes through the bi-metal component with impedance, if the current increases or the environment temperature rises and the temperature reaches the preset value, the bi-metal component will work and release the contact to shut off the circuit; and by contrast, if the device cools down to the safe temperature, the contact will close automatically to reset the normal work state.
