HED42B050 - 50Amp Circuit Breaker

HED42B050 - 50Amp Circuit Breaker

The Siemens HED42B050 is a 50 Amp, two-pole thermal magnetic circuit breaker designed for Siemens SENTRON low voltage molded case circuit breaker systems using the ED frame configuration. This breaker is commonly used when an existing electrical system requires a matching replacement with the same frame style, amp rating, voltage rating, and connection arrangement. For maintenance and repair work, having the correct breaker specifications helps keep your original equipment layout and wiring configuration unchanged.
