BEP Circuit Breaker Switches Airpax® magnetic circuit breakers are current sensing devices employing a time proven hydraulic magnetic design. They are temperature stable and the hydraulic-magnetic sensing mechanism reacts only to changes of current. There is no warm up or cool down period to slow response. VDE approved and UL recognised.
