HEB2B100B - 100Amp Circuit Breaker

HEB2B100B - 100Amp Circuit Breaker

The Siemens HEB2B100B is a 100 Amp, 2-pole molded case circuit breaker for use with compatible HEB (EG) frame low-voltage panelboards. When you're replacing a breaker in an existing installation, getting the specifications right is what matters most. The frame type, number of poles, amperage, voltage rating, and lug arrangement all need to match the original equipment. This breaker uses a thermal-magnetic trip unit to provide overload and short-circuit protection for applications requiring this HEB frame configuration.
