Working Principle:
Normally closed contact system, which is operated by a snap action of bimetal disc, is sensitive to current. When properly applied, protector shuts off the motor or the equipment 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.
