Overview
The Square D QO130EPD is a miniature circuit breaker designed to deliver overcurrent and equipment ground fault protection in single-phase AC and DC systems. This 30A, 1-pole plug-on breaker provides 30mA equipment ground fault protection for 120VAC systems. The plug-on design mounts into Square D QO load centers and NQ panelboards, making it a direct replacement solution for existing installations.
Key Features
