HEB2B070B - 70Amp Circuit Breaker

HEB2B070B - 70Amp Circuit Breaker

The Siemens HEB2B070B is a 70 Amp, 2-pole molded case circuit breaker designed for compatible HEB (EG) frame low-voltage panelboard applications. When you're replacing a breaker in an existing electrical system, the details matter — matching the frame style, pole count, amperage, voltage rating, and terminal configuration helps ensure the replacement is suited for the original installation. This model uses a thermal-magnetic trip unit to help provide overload and short-circuit protection while maintaining the specifications required for compatible Siemens equipment.
