Thermal protectors utilize a bimetallic strip electrically in series with the circuit. The heat generated by the current during an overload temporarily expands the bimetallic strip and trips the breaker. Thermal protectors can also be used as the main ON/OFF switch for the equipment being protected.
Highlighted by their versatility, Carling's thermal circuit breakers include lighted and non-lighted, rocker and push-to-reset actuator options with UL and European approvals. Typical applications inlcude household and commercial appliances, on/off-highway, marine, telecom, power strips and supplies, generators and audio-visual, medical and exercise equipment.
