Genuine Square D QO240 40 Amp Double Pole Circuit Breaker Kit UL Listed, Plug-On Replacement for QO Load Center Panel Box, 40A, 120/240V, 10kAIC, 40Amp, 2 Pole QO Circuit Breaker, 1 Pack

AUTHENTIC OEM COMPONENT This kit is built around one (1) factory-new, unused, and authentic Original Equipment Manufacturer (OEM) Square D QO240 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, known for its benchmark reliability and precise performance. Ideal for new construction, electrical system upgrades, or as a direct replacement part for existing Square D QO electrical systems. RELIABLE 40A OVERCURRENT PROTECTION This UL Listed two-pole breaker provides essential thermal-magnetic protection for high-power 40 Amp circuits.

It is engineered to safeguard expensive wiring and connected 240V equipment like sub-panels or large appliances from both sustained thermal overloads and instantaneous high-current short-circuit events. Its 10, 000 Ampere Interrupting Capacity (10kAIC) is specifically rated to safely handle significant fault currents found 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 appears 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 requiring any tools for diagnostics.

This simplifies the troubleshooting process for electricians and homeowners alike, significantly reducing downtime. 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. INSTALLATION KIT This is a value-added kit.

The box includes the genuine QO240 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
