HED42B025L - 25Amp Circuit Breaker

HED42B025L - 25Amp Circuit Breaker

The Siemens HED42B025L is a 25 Amp, two-pole thermal magnetic circuit breaker used in Siemens SENTRON low voltage molded case circuit breaker systems with the ED frame configuration. This breaker is commonly selected for maintenance and replacement projects where the existing electrical equipment requires a matching breaker with the same frame style, pole arrangement, ratings, and terminal setup. Keeping those details consistent helps maintain your original system layout and avoids unnecessary changes to existing wiring.
