HED41B020 - 20Amp Circuit Breaker

HED41B020 - 20Amp Circuit Breaker

The Siemens HED41B020 is a 20 Amp, one-pole thermal magnetic circuit breaker for Siemens SENTRON low voltage molded case circuit breaker systems using the ED frame style. This breaker is commonly used in maintenance and replacement work where the existing equipment requires the same breaker configuration, ratings, and connection style. With a 277V rating, 65kAIC interrupting capacity, and thermal magnetic trip unit, the HED41B020 provides circuit protection for compatible electrical systems while helping maintain your original panel setup.
