KSD9700-LH

The working principle of KSD9700-LH thermal protector is to use a fixed-temperature bimetallic disc as a sensitive reaction element.

When the temperature or current increases, the heat generated is transferred to the bimetallic disc. When the pre-setting temperature value is reached, it acts quickly to open the contacts and cut off the circuit.

When the temperature drops to the pre-setting reset value, the bimetal disc quickly recovers, closing the contacts and completing the circuit.

The long ceramic shell of this thermal protector can withstand a pressure of more than 40kg/cm2. It has the characteristics of small size, insulated ceramic shell, sensitive action, large contact capacity, long life, and rapid response to overheating and overheating.
