Circuit Protection
Proper protection is critical. Carling offers a full line of hydraulic-magnetic, thermal, and ground fault and equipment leakage circuit protection products. With a full complement of sizes and ratings providing current or voltage sensing, Carling's circuit protection products have you covered.


Hydraulic-Magnetic
Hydraulic Magnetic circuit breakers provide highly precise, reliable and cost effective solutions to most design challenges. They are considered temperature stable and are thus not appreciably affected by changes in ambient temperature. Their overcurrent sensing mechanism reacts only to changes of current in the circuit being protected. Carling offers a wide array of hydraulic/magnetic circuit breakers from .02 to 700 amps with UL, CSA, VDE, TUV, UL489, UL489A, UL1500 certifications.
Featured Products


Thermal
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, CSA and European approvals.


GFCI / ELCI
Carling's Ground Fault and Equipment Leakage Circuit Breakers combine the ground fault protection of a GFCI with the familiar overcurrent tripping characteristics of a normal circuit breaker.
