Hydraulic-Magnetic Circuit Breakers

Carling Technologies Hydraulic-Magnetic Circuit Breakers offer reliable, highly precise solutions to most design challenges and are available with multiple configurations. The circuit breakers are temperature stable and not appreciably affected by changes in ambient temperature, and their overcurrent mechanism only reacts to changes in current in the circuit being protected. These hydraulic-magnetic series from Carling Technologies offer multiple configuration options, advanced features, and cutting-edge designs that meet leading application requirements.
