The working principle and characteristics of thermal protector:

KW thermal protector is a kind of bimetal with constant temperature as a sensitive element. When the temperature or current rises, the heat generated is transferred to the bimetal disc, and when it reaches the rated operating temperature value, it will act quickly to disconnect the contacts and cut off the circuit; when the temperature drops

When the preset reset temperature setting value is reached, the bimetal disc will quickly recover, so that the contacts are closed and the circuit is connected.

The thermal protector has the characteristics of small size, large contact capacity, sensitive action and long life.
