HED42B030 - 30Amp Circuit Breaker

HED42B030 - 30Amp Circuit Breaker

The Siemens HED42B030 is a 30 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 for maintenance and replacement applications where the existing electrical equipment requires a matching breaker with the same frame style, pole configuration, voltage rating, and connection arrangement. Keeping these specifications consistent helps maintain your original panel setup and avoids unnecessary changes to the installed system.
