Overview
The Square D QO115DF is a 15 A, 120 V AC, single-pole QO dual-function circuit breaker for manufacturer-listed Square D QO load centers. It combines combination arc-fault and ground-fault protection with thermal-magnetic overcurrent protection, plug-in mounting, a pigtail neutral, and a 10 kA interrupting rating.
Key Features
-
Dual-function protection: Provides AFCI and GFCI protection in one exact-MPN breaker while retaining thermal-magnetic overcurrent protection.
-
Pigtail-neutral installation: Uses plug-in mounting with a pressure-plate load terminal and pigtail-neutral connection for compatible QO equipment.
-
QO compatibility: Designed for Square D QO load centers that are listed to accept the QO115DF configuration.
-
Branch-circuit rating: Rated 15 A at 120 V AC, one pole, with a 10 kA interrupting rating.
