HEB3B050B - 50Amp Circuit Breaker

HEB3B050B - 50Amp Circuit Breaker

The Siemens HEB3B050B is a 50 Amp, 3-pole molded case circuit breaker for compatible HEB (EG) frame low-voltage panelboard applications. When you're matching a replacement breaker, the small details make the difference. The frame type, number of poles, amperage, voltage rating, and terminal configuration all need to correspond with the existing equipment. This model includes a thermal-magnetic trip unit and load-side lugs (TA1EG10) for installations requiring this specific HEB frame arrangement.
