Must Have Siemens BF240A – 40A GFCI Molded Case Circuit Breaker

Built for commercial and industrial applications, the Siemens BF240A is a 40-amp, 2-pole ground fault circuit breaker. It provides reliable overcurrent protection for 120/240VAC electrical systems while safeguarding personnel against shock. This Type BLF breaker mounts into Siemens P1, P2, and P3 panelboards using a secure bolt-on connection. It serves as a direct replacement for the legacy BF240 model. Delivering a 10kAIC rating, it features Class A 5mA ground fault protection.
