Product FAQs
7 answersWhat panels is the Siemens BF120AH breaker compatible with?
This bolt-on circuit breaker mounts into Siemens P1, P2, and P3 commercial panelboards. It does not fit standard plug-on residential load centers.
What does the H in the BF120AH catalog number indicate?
The H designates a higher interrupting capacity. The standard BF120A model has a 10kAIC rating, while the BF120AH features a 22kAIC rating for commercial electrical systems with higher available fault currents.
What level of ground fault protection does the BF120AH provide?
This unit provides Class A ground fault protection. It is designed to trip when it detects a ground fault leakage current of 5mA, which is the standard requirement for personnel protection in wet or damp areas.
How is the pigtail neutral connected during installation?
The pre-attached coiled white pigtail wire must connect directly to the neutral bus bar in the panelboard. The neutral wire from the protected branch circuit then connects to the designated load neutral lug on the breaker itself.
Can I install this breaker in a residential Siemens load center?
No. The BF120AH features a bolt-on connection type specifically designed for commercial lighting and distribution panels. Standard residential load centers require plug-on QP or QPF style breakers.
Does the BF120AH include arc fault protection?
No. This unit provides thermal magnetic overcurrent protection and ground fault protection only. It does not detect arc faults.
Is the BF120AH considered a BLHF type breaker?
Yes. Under Siemens documentation, 1-pole 22kAIC bolt-on GFCI breakers in this physical frame size fall under the BLHF type classification.
