HEB3B110B - 110Amp Circuit Breaker

HEB3B110B - 110Amp Circuit Breaker

The Siemens HEB3B110B is a 110 Amp, 3-pole molded case circuit breaker for compatible HEB (EG Frame) low-voltage panelboard applications. When you're replacing an existing breaker, the most important factor is matching the original equipment specifications. The frame style, pole configuration, amp rating, voltage rating, and lug arrangement all need to align with the installed system. This model includes a thermal-magnetic trip unit and load-side lugs (TA1EG10) for applications requiring this specific HEB frame configuration.
