Built for commercial and industrial applications, the Square D QOB130VHGFI is a 1-pole, 30A bolt-on circuit breaker delivering Class A 6mA ground fault protection. It features a pigtail neutral connection for reliable performance in wet or damp locations requiring NEC compliance. This unit installs into Square D NQ and NQOD panelboards. It includes a Visi-Trip indicator for quick fault identification. Rated at 22 kAIC at 120VAC, this QOB-VH series breaker ensures robust protection.
Can I install the QOB130VHGFI in a standard QO load center?
No. The QOB130VHGFI is a bolt-on circuit breaker designed specifically for NQ and NQOD panelboards. For a standard plug-on QO load center, you must use the plug-on equivalent, catalog number QO130VHGFI.
What does the VH stand for in the QOB130VHGFI catalog number?
The VH indicates a high-interrupting rating. While standard QOB breakers are rated for 10kAIC, the VH version is rated for 22kAIC at 120V to safely handle higher available fault currents.
How is the neutral wired on the QOB130VHGFI?
This breaker uses a pigtail neutral. The attached white coiled wire must be routed and secured to the neutral bar in the panelboard to power the internal GFCI circuitry.
What class of GFCI protection does the QOB130VHGFI offer?
It provides Class A GFCI protection for personnel. The breaker is calibrated to trip when it detects a ground fault of 6 milliamperes or greater, protecting users from electrical shock.
Does the QOB130VHGFI provide arc-fault protection?
No. This model is strictly a Ground-Fault Circuit Interrupter (GFCI). It does not provide Arc-Fault Circuit Interrupter (AFCI) or dual-function protection.
Does the QOB130VHGFI feature a tripped indicator?
Yes. Like most Square D QO and QOB breakers, it includes a Visi-Trip indicator. When the breaker trips due to an overload, short circuit, or ground fault, a red indicator appears in the window to help quickly identify the tripped circuit.
