Schneider Electric’s Square D QOB120VHGFI is a 20 A, 1-pole QO-series miniature circuit breaker with built-in ground-fault protection (GFI). It is designed for 120 V AC circuits and provides a 22 kA RMS interrupt rating, suitable for bolt-on mounting in compatible panel systems. This GFI breaker features a 6 mA ground-fault trip threshold and a pigtail lead, delivering sensitive protection for branch circuits in residential and commercial distributions where rapid disconnection on leakage is required.
