Thermal Circuit Breakers

Thermal circuit protectors utilize a bimetallic strip electrically in series with the circuit. The heat generated by the current during an overload deforms the bimetallic strip and trips the breaker. Thermal protectors can also be used as the main ON/OFF switch for the equipment being protected. Carling offers a variety of 3 to 60 amp, lighted and non-lighted, rocker actuator and push-to-reset push button thermal circuit breakers with UL, CUL, CE, UL1500/ISO 8846 certifications.
