HED42B070 - 70Amp Circuit Breaker

HED42B070 - 70Amp Circuit Breaker

The Siemens HED42B070 is a 70 Amp, 2-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 when your existing electrical installation requires a matching replacement with the same frame style, amp rating, voltage rating, and terminal arrangement. For maintenance and repair work, finding the correct breaker is about more than just matching the amperage — the frame, poles, connection style, and electrical ratings all need to fit the existing equipment.
