Square D QO315GFI Ground Fault Circuit Breaker – 15A – 3 Pole – 208Y/120VAC – Plug-On – 6mA GFCI – QO Series

The Square D QO315GFI is a QO-series three-pole ground fault circuit interrupter (GFCI) breaker designed for commercial and industrial 208Y/120VAC systems. It provides thermal magnetic protection combined with 6mA ground fault detection for enhanced personnel and equipment safety. Featuring a Visi-Trip indicator, this breaker allows fast identification of tripped conditions. It installs into standard Square D QO load centers and NQ panelboards using a plug-on connection and includes a pigtail neutral for proper GFCI operation.
