Product FAQs
5 answersWhat is the difference between the Siemens BF240A and BF240AH?
The "H" in the BF240AH catalog number indicates a high interrupting rating. The BF240AH is rated for 22kAIC at 120/240VAC, whereas the standard BF240A is rated for 10kAIC.
What level of ground fault protection does the BF240AH provide?
This breaker provides Class A ground fault protection, which trips when it detects a ground fault of 5mA (milliamps). This level of protection is designed to protect personnel from electrical shock in wet or damp locations.
Can I install the BF240AH in a standard Siemens load center?
No. The BF240AH features a bolt-on connection designed specifically for Siemens P1, P2, and P3 commercial panelboards. It will not fit in standard plug-on residential load centers like the EQ or PL series.
How is the neutral connection handled on this GFCI breaker?
The BF240AH includes a pigtail neutral wire. During installation, this pigtail must be securely connected to the panelboard's neutral bar to power the breaker's internal ground fault circuitry and ensure proper operation.
Is the BF240AH rated for HACR applications?
Yes, this breaker is HACR rated, meaning it is approved for use with heating, air conditioning, and refrigeration equipment that requires this specific designation.
