Square D Qwik Open 50A 2-Pole Mini Circuit Breaker – 120/240V AC, 10kA, Plug-in Mount (QO250CP)

Overview

The Square D by Schneider Electric Qwik Open 50 Amp Mini Circuit Breaker is designed to deliver dependable protection for both residential and commercial panels. With an over-center, trip-free toggle, it provides quick make and quick break action, helping to minimize nuisance interruptions and simplify electrical maintenance. Its plug-on neutral design helps streamline installation in compatible Square D QO load centers, occupying two spaces in the panel for a compact footprint. A built-in Visi-Trip indicator offers a clear visual cue when the breaker has tripped, helping technicians identify issues quickly without resorting to extensive testing.

Operating at 120/240V AC and rated for 50A with a 10kA breaking capacity, this device blends safety and reliability in a UL-listed, CSA-certified package. The combination of thermal magnetic protection provides fast response to overcurrent conditions, potentially reducing the risk of damage to connected circuits and equipment. The result is a robust protection solution that is suitable for a range of standard electrical setups, from home forums to small business installations.

Key advantages
