Product FAQs
6 answersWhat does the H in the B230GFH catalog number indicate?
The H designates a high interrupting rating. While the standard B230GF has a 10kAIC rating, the B230GFH is rated to safely clear faults up to 22kAIC at 120/240VAC.
Is this breaker designed for personnel or equipment ground-fault protection?
The B230GFH is a Class A GFCI breaker designed for personnel protection. It will trip when it detects a ground fault of 5mA to help prevent electrical shock, unlike equipment protection (EP) devices that trip at 30mA.
How is the neutral wired on the B230GFH GFCI breaker?
This model features a pigtail neutral connection. The coiled white pigtail wire must be connected directly to the panelboard neutral bar, while the load neutral wire connects directly to the breaker load-side neutral lug.
Can I use this breaker in a standard residential load center?
No. The B230GFH features a bolt-on connection designed specifically for commercial and industrial panelboards, such as the Siemens P1 through P5 series. It cannot be installed in standard plug-on load centers.
Can the B230GFH be used to replace obsolete ITE GFCI circuit breakers?
Yes. Siemens acquired ITE, and the modern Siemens B230GFH serves as the direct drop-in replacement for the obsolete ITE BF230AH 30A, 2-pole, 22kAIC GFCI breaker.
What if my application requires an interrupting rating higher than 22kAIC?
If the available fault current in your system exceeds 22kAIC, you must step up to the B230GFHH model, which provides a 65kAIC rating. The 22kAIC-rated B230GFH cannot be used in systems exceeding its rating.
