Siemens BE120 20A 1P 120V Circuit Breaker, GFCI, Bolt-On | AmpState

The Siemens BE120 20A 1P 120V GFCI Bolt-On Circuit Breaker is built for everyday electrical work, delivering reliable circuit protection in panelboards, load centers, and distribution panels. Its bolt-on design keeps retrofit projects smooth and maintenance planning straightforward when the part number needs to stay consistent.

Engineered with a ground-fault circuit interrupter (GFCI), this 1-pole breaker instantly shuts off power if a ground fault is detected, reducing the risk of shock for circuits that feed outlets in kitchens, bathrooms, basements, garages, and outdoor spaces. At 120 volts and 20 amps, it provides targeted protection for residential and light commercial circuits without bulky changes to your panel lineup.

Available from AmpState.
