Thermal Protector

Thermal Protector

Working Principle:
Normally closed contact system, which is operated by a snap action of bimetal disc, is sensitive to both temperature and current. When properly applied, protector shuts off the motor when temperature exceeds maximum safe level due to an overload or stalled (locked rotor) condition. The greater the work current of motor is, the shorter time the cutting off power needs.
