HED41B070L - 70Amp Circuit Breaker

HED41B070L - 70Amp Circuit Breaker

The Siemens HED41B070L 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 replacement and maintenance projects where the existing equipment requires a matching breaker with the same frame style, electrical ratings, and terminal setup. When you're working with an established electrical system, the right replacement comes down to the details — matching the breaker already installed helps maintain the original panel arrangement and wiring configuration.
