HED42B100 - 100Amp Circuit Breaker

HED42B100 - 100Amp Circuit Breaker

The Siemens HED42B100 is a 100 Amp, 2-pole thermal magnetic circuit breaker used in Siemens SENTRON ED frame electrical distribution equipment. This breaker is typically selected when your existing installation requires a matching replacement with the same breaker style, electrical ratings, and connection arrangement. For maintenance and repair work, getting the details right is important — the frame type, amp rating, voltage, pole configuration, and lug setup all need to match the equipment already in service.
