A motor circuit breaker (sometimes also referred to as a thermal circuit breaker, thermistor or PKZ) is an electromechanical switching device with a protective purpose, whose main task is to protect an electric motor from the negative effects of short circuits, overloads and phase loss in a three-phase network. Due to their protective function, motor circuit breakers are used wherever various types of machinery powered by electric motors are used, such as pumps, machine tools, compressors, extractors, production belts, ventilation systems and heavy construction equipment.
