HEB1B080B - 80Amp Circuit Breaker

HEB1B080B - 80Amp Circuit Breaker

The Siemens HEB1B080B is an 80 Amp, single-pole molded case circuit breaker designed for use with compatible HEB (EG) frame low-voltage panelboards. When you're replacing a breaker in an existing installation, it is important to match the frame style, amperage, voltage rating, and terminal arrangement. This model uses a thermal-magnetic trip unit to provide overload and short-circuit protection while maintaining the specifications of the original equipment.
