HEB2B025B - 25Amp Circuit Breaker

HEB2B025B - 25Amp Circuit Breaker

The Siemens HEB2B025B is a 25 Amp, 2-pole molded case circuit breaker used in compatible HEB (EG) frame low-voltage panelboards. When you're replacing a breaker in an existing system, the small details make the difference — pole count, amperage, voltage rating, and lug configuration all need to match. This model uses a thermal-magnetic trip unit to help protect your electrical circuits from overloads and short circuits while keeping the original panelboard setup unchanged.
