Hydraulic-magnetic circuit breakers are considered temperature stable and are not appreciably affected by changes in ambient temperature. Their overcurrent sensing mechanism reacts only to changes of current in the circuit being protected. Well known for their performance and reliability, each series in Carling’s selection of hydraulic-magnetic circuit breakers are available with multiple configuration options and many offer advanced features and cutting-edge designs to meet today’s leading application requirements. Custom actuator colors and non-standard amp offerings are also available for most hydraulic-magnetic circuit breaker series. Click a specific hydraulic-magnetic circuit breaker series below to learn more, use the eParts catalog with its parametric filters to view and compare standard part numbers that meet your specifications or configure a complete and valid part number with our online Configurit® tool.
