HHED63B045 - 45Amp Circuit Breaker

HHED63B045 - 45Amp Circuit Breaker

The Siemens HHED63B045 is a 45 Amp, 3-pole SENTRON molded case circuit breaker built on the ED frame with a thermal-magnetic trip unit. It’s intended for your electrical equipment that calls for this specific combination of amperage, pole count, frame size, interrupting rating, and terminal arrangement. When the frame, poles, voltage, interrupting capacity, lug setup, conductor range, and dimensions align with the equipment requirements, the HHED63B045 provides the intended form, fit, and electrical function. Its molded case construction is built to last when properly installed and used within its stated ratings.
