Schneider Electric QO245GFI Ground Fault Circuit Breaker

Schneider Electric's QO245GFI is a two-pole, 45-amp ground-fault circuit interrupter (GFCI) breaker designed for 120/240-volt circuits, a member of the Square D QO family built for residential and light commercial panels where robust GFCI protection is required. As a plug-on GFI device, it combines overcurrent protection with Class A ground-fault protection at a 6 mA trip threshold, enabling rapid detection of leakage currents that could pose shock hazards while remaining compatible with standard QO accessories and enclosures. The unit carries a 10 kA interrupt rating at 120/240 VAC, suitable for typical feeder and branch-circuit applications, and is specified for feeding 240 VAC and 208 VAC two-wire loads in QO load centers. With its 45-amp rating, the QO245GFI supports high-current circuits such as large appliances or workshop equipment where ground-fault protection is a priority, offering reliable protection without sacrificing compatibility with widely used Square D components.
