Description
Built for commercial and industrial environments, this 30A single-pole GFCI breaker provides essential 6mA ground-fault protection. It utilizes a thermal-magnetic trip mechanism to safeguard 120VAC electrical circuits against overloads and short circuits. This bolt-on unit installs into Square D NQ and NQOD panelboards, ensuring a rigid and reliable bus connection. For applications requiring a higher interrupting capacity, the QOB130VHGFI serves as a direct substitute.Specifications

Product FAQs
6 answersCan I install the QOB130GFI in a standard residential QO load center?
No. The QOB130GFI has a bolt-on connection designed specifically for commercial NQ and legacy NQOD panelboards. Standard residential QO load centers require a plug-on breaker such as the QO130GFI.
How does the pigtail neutral work on this breaker?
The white coiled pigtail wire must be connected directly to the panelboard neutral bar. This connection powers the internal GFCI circuitry, allowing the breaker to accurately monitor current balance and detect ground faults.
What level of ground fault protection does this breaker provide?
This breaker provides Class A ground fault protection. The internal circuitry is calibrated to trip when it detects a ground fault current of 4 to 6 milliamperes, which provides primary personnel protection against electrical shock.
Does this breaker provide arc fault protection?
No. The QOB130GFI is exclusively a Ground Fault Circuit Interrupter (GFCI). It does not provide Combination Arc Fault (CAFI) or Dual Function (DF) protection. If arc fault mitigation is required by code, you will need a different breaker type.
Can I use the QOB130GFI to protect a 240V circuit?
No. This is a 1-pole breaker rated strictly for 120V AC applications. A 2-pole QOB breaker is required for 240V equipment or multi-wire branch circuits.
Is there a 22kAIC version available if my panel requires a higher short circuit rating?
Yes. If your electrical system requires a 22kAIC interrupting rating, you must use the QOB130VHGFI instead of this standard 10kAIC model.

Great price. Fast delivery. My local electric distributor wanted double for the same breaker, so it was a no brainer to order this one. Ordered another one since with the same great service.
