Molded Case Circuit Breakers

Most molded case circuit breakers made today are thermal magnetic, which means that, for overcurrents below a specified value the trip time is current dependent (thermal element trips breaker) and magnetic for currents above a specified level. Shop from switch manufacturers producing molded case circuit breakers, earth leakage circuit breakers, magnetic starters, fuses, control switches and sensitive devices. The case of the circuit breaker functions as both an outer wrapper and to retain in proper position the breaker’s internal components.
