HED41B030L - 30Amp Circuit Breaker

HED41B030L - 30Amp Circuit Breaker

The Siemens HED41B030L is a 30 Amp, one-pole thermal magnetic circuit breaker built for Siemens SENTRON low voltage molded case circuit breaker systems using the ED frame configuration. When your existing electrical system needs a matching replacement breaker, the details matter — the correct frame style, amperage, voltage rating, and terminal arrangement all need to line up. The HED41B030L is commonly used in maintenance and replacement work where keeping the original equipment setup unchanged is important.
