HEB3B080B - 80Amp Circuit Breaker

HEB3B080B - 80Amp Circuit Breaker

The Siemens HEB3B080B is an 80 Amp, 3-pole molded case circuit breaker for compatible HEB (EG Frame) low-voltage panelboard installations. When you're replacing a breaker in an existing system, matching the original equipment is key. The frame type, pole count, amperage, voltage rating, and lug arrangement all need to line up with the breaker being replaced. The HEB3B080B includes a thermal-magnetic trip unit and load-side lugs (TA1EG10) to match applications requiring this specific HEB frame configuration.
