Product details:

Qwik-Gard? Ground-Fault Circuit Interrupters offer a means of providing ground-fault protection for people. Qwik-Gard ?people protection? ground-fault circuit interrupters are built as Class A devices in accordance with UL Standard 489 and CSA C22.2 #144 for ground-fault circuit interrupters (GFCIs). Class A devices must trip at 6 milliamperes of ground-fault current and above, and hold below 4 milliamperes of ground-fault current. Qwik-Gard GFCIs provide the same branch circuit protection as standard QO circuit breakers. They are longer than standard QO circuit breakers, and thus require more gutter space. All QO electrical accessories except shunt trip and all QO mechanical accessories are available for QO-GFI and QOBGFI circuit breakers. Qwik-Gard circuit breakers are UL Listed and CSA Certified and available in both one- and two-pole constructions.
