Schneider Electric QOB315GFI Ground Fault Circuit Breaker

Schneider Electric QOB315GFI is a bolt-on, three-pole ground-fault circuit interrupter (GFCI) breaker rated for 15 A in 208Y/120 VAC three-phase systems. With a 10 kA interrupt rating, it protects feeders and branch circuits from overloads and short circuits while providing Class A ground-fault protection at 6 mA. The unit includes a neutral pigtail for wiring convenience and is designed for use in QO-based panelboards, including NQ and NQOB interiors. This 3P GFI breaker fits bolt-on installations and is intended for commercial power distribution where ground-fault protection is required on 3-phase circuits. The combination of bolt-on mounting, 3P configuration, and GFCI sensing helps reduce shock risk for equipment and personnel in environments with three-phase loads, while meeting safety codes that require ground-leakage protection on three-phase distribution.
