Working principle of 7AM thermal protector

The core of the 7AM small thermal protector is the kick-type bimetal disc. The current passes through the bimetal element. When the current increases or the ambient temperature rises to the set temperature value, the bimetal element moves quickly, opens the contact, and cuts off the circuit. When the device cools down to a safe operating temperature, the bimetal reed quickly resets, the contacts close automatically and power is restored.
