HED41B020L - 20Amp Circuit Breaker

HED41B020L - 20Amp Circuit Breaker

The Siemens HED41B020L is a 20 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 commonly used for replacement and maintenance work where the existing electrical equipment requires the same breaker style, ratings, and connection arrangement. With a 277V rating, 65kAIC interrupting capacity, and thermal magnetic trip unit, the HED41B020L provides circuit protection for compatible electrical distribution systems while helping preserve your original installation design.
