Overview
The Square D QO120PDF is a 20 A, 120 VAC, single-pole dual-function breaker for compatible QO plug-on-neutral load centers. It combines combination arc-fault and Class A ground-fault protection with thermal-magnetic overload and short-circuit protection in one 10 kAIC device.
Key Features
-
Protection: Dual-function protection addresses both hazardous series/parallel arc faults and personnel-protection ground faults, reducing the need for separate AFCI and GFCI devices.
-
Installation: Its plug-on-neutral design connects directly to the neutral bar in compatible QO equipment; the pressure-plate load terminal accepts the branch conductor without a neutral pigtail.
-
Compatibility: Use only with Square D QO plug-on-neutral load centers or other equipment specifically labeled for QO120PDF.
-
Performance: Rated 20 A, 1 pole, 120 VAC and 10 kAIC for circuits that require both AFCI and GFCI protection.
