Product FAQs
7 answersCan the B330GFHH be used in standard residential load centers?
No. The B330GFHH is a bolt-on circuit breaker intended for commercial and industrial Siemens P1 panelboards. It will not fit in standard plug-on residential load centers.
Does the Siemens B330GFHH provide Class A personnel protection or equipment protection?
This breaker provides Class A 5mA ground fault circuit interruption (GFCI) designed specifically for personnel safety. It trips when leakage current exceeds the 5mA threshold.
Does the B330GFHH require balanced loads across all three phases to prevent false ground fault tripping?
No. Siemens 3-pole GFCI breakers monitor residual differential current to detect leakage. They do not require a perfectly balanced phase load for the ground fault detection to operate correctly.
How is the neutral connection configured on the B330GFHH?
This GFCI breaker comes equipped with a pigtail neutral wire. The pigtail must be terminated at the panel neutral bar to provide a reference point and power the internal ground fault sensing circuitry.
What is the Siemens breaker type designation for the B330GFHH?
The B330GFHH is classified as a Type HBQDPF breaker within the Siemens B-frame family.
What does the HH suffix indicate on the B330GFHH catalog number?
The HH designation signifies a high interrupting rating. For the Siemens B-frame GFCI line, the HH suffix specifically indicates a maximum interrupting capacity of 65kAIC at 240VAC.
Does the B330GFHH include a self-testing feature?
Yes. To comply with UL 943 standards for Class A GFCI devices, this breaker includes an automated self-test function that continuously verifies the internal ground fault circuitry is operating correctly.

I ordered breakers from this company. They were fast and prompt on the initial order. I ended up returning part of the order as I did not need those breakers. To say the very least I am not satisfied with the return process. They do not respond to emails and will not return a phone call. I'm still waiting on the partial refund for these items as their restocking fee is ridiculously high. Please make sure you are buying what you need from this company as the return process is painful ,frustrating and costly.
