Circuit Breakers and Power Switches

Hydraulic-Magnetic circuit breakers are used when precision is critical. Their overcurrent protection performance is largely independent of the ambient temperature within the specified operating range and can be fine-tuned to 1/10 of an ampere. These circuit breakers can also be made to compensate for transient conditions such as the motor inrush currents, to avoid nuisance tripping.

Sensata offers a wide variety of packages, mounting types, terminations, handle types and other features to construct the ideal solution for each application. Our Circuit Breakers are both recognized and listed by globally recognized agencies such as UL, TUV, CCC, CSA and Military Standards.  Our portfolio accommodates current ratings from 0.1 to 1,200A.
