HEB2B030B - 30Amp Circuit Breaker

HEB2B030B - 30Amp Circuit Breaker

The Siemens HEB2B030B is a 30 Amp, 2-pole molded case circuit breaker designed for compatible HEB (EG) frame low-voltage panelboards. When you're replacing an existing breaker, the right match comes down to the details — frame type, pole configuration, amperage, voltage rating, and terminal setup all need to align with the original installation. This model features a thermal-magnetic trip unit to help protect your circuits from overloads and short circuits while fitting the requirements of compatible Siemens equipment.

Built to last, the Siemens HEB2B030B is a straightforward replacement component for maintaining established commercial and industrial electrical distribution systems.
