    Breaker Review

    Very good equipment and was in great condition.

    Also does SuperBreakers purchase any new in box breakers?

    Siemens ED43B040 3 Pole Circuit Breaker.

    I initially purchased two Siemens ED43B040 3-pole circuit breakers. One of the breakers wouldn’t engage properly, so I returned it. The return process was smooth, and a replacement breaker was delivered overnight. It’s always a pleasure doing business with Super Breaker.
