HED41B050 - 50Amp Circuit Breaker

HED41B050 - 50Amp Circuit Breaker

The Siemens HED41B050 is a 50 Amp, one-pole thermal magnetic circuit breaker designed for Siemens SENTRON low voltage molded case circuit breaker systems using the ED frame configuration. This breaker is identified by its 50 Amp rating, 277V voltage rating, 25kAIC interrupting capacity, and load lug connection style, making it a specific match for compatible electrical equipment requiring these specifications. When you're working on existing installations, selecting the correct breaker comes down to matching the original frame, ratings, and terminal arrangement rather than changing the system design.
