Genuine Square D QO250 Circuit Breaker Kit, 50 Amp (50A) Double Pole (2 Pole), 120/240V AC, 10kAIC, Plug-in Mount for QO Load Centers & Panels, Visi-Trip Indicator, New Replacement

GENUINE OEM COMPONENT This kit is built around one (1) factory-new, unused, and authentic Original Equipment Manufacturer (OEM) Square D QO250 circuit breaker. The QO series is Square D's premium, professional-grade line of circuit protection. This component is sourced to deliver genuine Square D technology, recognized for its benchmark dependability and precise operation. Ideal for new construction, electrical system upgrades, or as a direct replacement component for existing Square D QO electrical systems, ensuring a perfect fit and function. RELIABLE 50A OVERCURRENT PROTECTION This UL Listed two-pole breaker delivers essential thermal-magnetic protection for high-power 50 Amp circuits.

It is engineered to protect expensive wiring and connected 240V equipment such as electric ranges or sub-panels from both sustained thermal overloads and instantaneous high-current short-circuit events. Its 10, 000 Ampere Interrupting Capacity (10kAIC) is specifically rated to safely manage significant fault currents present in typical 120/240V AC 60Hz residential electrical services. EXCLUSIVE VISI-TRIP INDICATOR Features the signature Square D Visi-Trip indicator, a red flag that shows in a dedicated window on the breaker's face during a trip event. This industry-leading function allows for immediate visual identification of the specific faulted circuit from the front of a busy panel without needing any tools for diagnostics.

This streamlines the troubleshooting process for electricians and homeowners alike, greatly reducing downtime when restoring power to critical loads or major appliances. QO SYSTEM COMPATIBILITY & SPECIFICATIONS Designed with a robust plug-in mount for exclusive use in Square D QO-series load centers, panelboards, and CSEDs (Combined Service Entrance Devices) which feature the shielded copper bus bar system. The box lug terminals accept a wide wire size range of #8 to #2 AWG for both aluminum (Al) and copper (Cu) conductors and require a tightening torque of 45 lb-in. This component is UL Listed and CSA Certified, meeting rigorous North American safety and performance standards.

INSTALLATION KIT This is a value-added installation kit. The box contains the genuine QO250 breaker, one (1) packet of AGS dielectric grease for terminal lug and bus bar contact lubrication, and one (1) Pro-Finishing Hardware Pack containing two professional-grade, zinc-plated steel combination-drive panel cover machine screws and one green hex-head grounding machine screw for convenience
