HEB3B100B - 100Amp Circuit Breaker

HEB3B100B - 100Amp Circuit Breaker

The Siemens HEB3B100B is a 100 Amp, 3-pole molded case circuit breaker for compatible HEB (EG Frame) low-voltage panelboard applications. Finding the right replacement for your breaker is about more than matching the amp rating. The frame style, number of poles, voltage rating, and lug configuration all need to match the existing equipment. The HEB3B100B features a thermal-magnetic trip unit and load-side lugs (TA1EG10), making it a suitable option for applications that require this specific HEB frame configuration.
