Square D by Schneider Electric Qwik Open 50A 2-Pole Mini Circuit Breaker – 120/240V, 10kA, Plug-on Neutral

Compact, reliable protection for home and business electrical systems

The Square D by Schneider Electric Qwik Open 50 Amp Mini Circuit Breaker is designed to guard circuits with a quick make, quick break action. Its over-center, trip-free toggle delivers an instantaneous disconnect when overcurrent or short-circuit conditions occur, helping to minimize potential damage to connected equipment and wiring while you monitor the rest of the panel with confidence.

The design emphasizes simple installation. The plug-on neutral design fits neatly into Square D QO load centers and CSEDs, occupying two spaces and supporting a fast, hassle-free setup. For technicians and handy homeowners alike, this means a streamlined replace-and-run process that reduces panel downtime during upgrades or maintenance.

Clear visibility, faster troubleshooting

A built-in Visi-Trip indicator provides an immediate visual cue when the breaker has tripped. This small but valuable feature can speed diagnostics and maintenance by letting you identify the tripped state without removing panel covers or testing wires.

Smart protection with quick response

Equipped with thermal magnetic technology, the Qwik Open 50 A breaker responds rapidly to overcurrent conditions. The result is prompt interruption of faulty circuits, helping protect connected appliances, fixtures, and wiring from prolonged exposure to faults in both 120 and 240 volt circuits.
