New Release Siemens BF120A – 20A GFCI Molded Case Circuit Breaker

Part of the modern Siemens lineup, the BF120A is a 20-amp, single-pole GFCI breaker designed for commercial electrical systems. Operating at 120VAC, it provides critical 5mA Class A ground fault protection for wet locations. This bolt-on breaker installs into Siemens P1, P2, and P3 panelboards and serves as the drop-in replacement for older BF120 models. Rated at 10kAIC, it features an automated self-test function that periodically verifies the internal ground fault circuitry is working.
