HEB1B045B - 45Amp Circuit Breaker Description
HEB1B045B - 45Amp Circuit Breaker
Keeping your existing electrical system operating safely often comes down to using the right replacement breaker. The Siemens HEB1B045B is a 45 Amp, 1-pole molded case circuit breaker made for compatible HEB (EG) frame panelboards. It uses a thermal-magnetic trip mechanism to help protect your circuits from overloads and short circuits, making it a dependable choice for routine maintenance, repairs, and replacement projects. Factory-installed load-side lugs (TA1EG10) accept 8 AWG through 1/0 AWG copper or aluminum conductors, helping simplify installation in compatible systems. Like other Siemens molded case breakers, the HEB1B045B is built to last and is intended for long-term service in existing electrical distribution equipment.
