The thermal protector is a combination of two different alloys, which will generate heat after passing the current. Due to the different thermal expansion coefficients of the two different alloys, the alloy will inevitably bend in one direction, and the contact will be disconnected, which can protect the electrical equipment .
KSD9700 series product is a kind of thermostat that uses bimetal as the temperature sensing element. When the temperature drops to the set temperature, the contact automatically closes/opens and resumes normal operation. Widely used in household appliances motors and electrical equipment, such as washing machine motors, air conditioner fan motors, transformers, ballasts, electric heating appliances, etc.
