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 have a significant advantage over fuses in that they can be reset after tripping. They 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.
