HED42B100L - 100Amp Circuit Breaker

HED42B100L - 100Amp Circuit Breaker

The Siemens HED42B100L is a 100 Amp, 2-pole thermal magnetic circuit breaker designed for Siemens SENTRON ED frame electrical distribution equipment. This molded case circuit breaker is commonly used when an existing installation requires a replacement breaker that matches the original electrical specifications, including frame type, amperage, voltage rating, pole configuration, and lug arrangement. With a 480V rating, 42kAIC interrupting capacity, and line and load-side lugs, the HED42B100L is built for your applications where maintaining the existing breaker setup is important.
