Description

Integrating automated self-test capabilities, the BF250A delivers 50A of Class A ground fault protection for commercial electrical systems. This two-pole device continuously monitors its own functionality to ensure reliable 5mA leakage detection in NEC-mandated damp locations. Designed for secure bolt-on installation, it mounts into Siemens P1, P2, and P3 panelboards. It replaces the older BF250 and is succeeded by the B250GF. This HACR-rated breaker provides a 10kAIC interrupting capacity.

Product FAQs

8 answers
What level of ground fault protection does the Siemens BF250A provide?

The BF250A provides Class A, 5mA ground fault protection. It is designed for personnel protection in wet or damp locations such as spas, pools, bathrooms, and commercial kitchens, complying with NEC requirements.

Does the BF250A include an automated self-test function?

Yes. To meet modern safety standards, the BF250A continuously monitors its internal ground fault circuitry with an automated self-test feature to ensure reliable 5mA leakage detection is always active.

Can I install the BF250A in a standard plug-on residential load center?

No, the BF250A features a bolt-on mounting style specifically for Siemens P1, P2, and P3 commercial panelboards. If you need a 50A GFCI for a plug-on Siemens EQ load center, you will typically need a Type QPF2 breaker like the QF250A.

How is the neutral connection wired on this GFCI breaker?

This unit uses a pigtail neutral connection. The white coiled pigtail wire connects directly to the panelboard neutral bus, while the neutral wire from your load connects directly to the load neutral terminal on the breaker itself.

What is the difference between the Siemens BF250A and the BE250?

The BF250A is a Class A GFCI that trips at a 5mA threshold for personnel protection. The BE250 is a Ground Fault Equipment Protection (GFEP) breaker that trips at a 30mA threshold to prevent nuisance tripping on equipment like heat trace cables or pumps.

Will the BF250A replace older BF250 breakers?

Yes. The BF250A serves as a direct drop-in replacement for legacy BF250 breakers. It maintains the identical bolt-on footprint for P-series panels while adding updated self-testing capabilities.

Do the terminal lugs accept both copper and aluminum wire?

Yes, the load-side lugs are dual-rated for both materials. They accept 8 AWG to 6 AWG copper conductors, and 8 AWG to 4 AWG aluminum conductors.

Is this breaker HACR rated for HVAC applications?

Yes. The BF250A is HACR rated, meaning it is approved for use with heating, air conditioning, and refrigeration equipment that requires a 50A ground fault protected circuit.
