Hydraulic/Magnetic Circuit Breaker


Carling Technologies' C-Series hydraulic magnetic circuit breakers are designed for those applications requiring higher amperage and voltage handling capability in a smaller package. The C-Series UL489 circuit breakers employ a unique arc chute design, which results in obtaining higher interrupting capacities, up to 10,000 amps. Several actuator styles including sealed toggle, handle, rocker, visi-rocker with optional mid-trip handle and exclusive Rockerguard and Push-To-Reset bezel, which help prevent inadvertent actuation, are available.

1-6 poles; ratings from 0.02-100amps, up to 480VAC or 80VDC & up to 240VAC or 125VDC for UL489 configurations; UL recognized, CSA, VDE -0642, UL1500, TUV, UL489 Listed, UL489A Listed
