Product FAQs
5 answersWhat level of ground fault protection does the Siemens BF125AH provide?
It provides Class A ground fault protection, tripping at a 5mA threshold to protect personnel from electrical shock in wet or damp locations.
What is the difference between the Siemens BF125AH and the standard BF125A?
The H in the BF125AH catalog number designates a high interrupting rating. The BF125AH is rated for 22kAIC at 120VAC, while the standard BF125A is rated for 10kAIC.
Can I install the BF125AH in a standard residential load center?
No. The BF125AH is a bolt-on breaker designed exclusively for commercial Siemens P1, P2, and P3 panelboards. Standard residential load centers typically require plug-in breakers like the QPF series.
How is the neutral connection established for this GFCI breaker?
The BF125AH is equipped with a pigtail neutral wire. This wire must be routed and connected directly to the neutral bar in the panelboard to power the ground fault detection circuitry.
Can the BF125AH replace a standard BLH circuit breaker?
Yes, it can replace a standard 1-pole BLH bolt-on breaker in compatible Siemens panels when a 25A circuit requires an upgrade to include ground fault protection.
