Overview
The Square D QO120DF is a 20 A, single-pole dual-function circuit breaker for compatible QO load centers. It combines combination arc-fault and Class A ground-fault protection for 120 V circuits with a 10 kA interrupting rating. The existing consumer-package GTIN is retained under package MPN QO120DFC.
Key Features
-
Protection: Dual-function AFCI/GFCI protection detects hazardous arcing and ground-fault conditions while thermal-magnetic protection responds to overloads and short circuits.
-
Installation: Plug-in mounting with a pressure-plate load terminal, pigtail-neutral connection, and a 14–8 AWG copper or aluminum conductor range.
-
Compatibility: For compatible Square D QO load centers; QO120DFC denotes the consumer-packaged form of QO120DF.
-
Performance: 20 A single-pole protection at 120 V AC with a 10 kA interrupting rating and a 104°F (40°C) ambient rating.
