HED41B070 - 70Amp Circuit Breaker

HED41B070 - 70Amp Circuit Breaker

The Siemens HED41B070 is a 70 Amp, one-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 equipment requires a matching breaker with the same frame style, electrical ratings, and connection setup. When you're working with an installed electrical system, keeping the original design intact often comes down to finding the correct breaker match.
