Description
QO Load Centers offer premium features by allowing QO breakers, ground fault interrupters, arc fault interrupters, and surge arresters to be installed inside. QO Load Centers are designed for residential and industrial use to protect electrical systems, equipment, and people. They are available in both traditional and plug on neutral configurations. There is 3 types of mains available. There is main circuit breaker, main lugs, and generator panel. Single and three phase options are available. The bus bars are tin plated copper and are shielded. Indoor and outdoors enclosures are an option. QO Load Centers enable the use of a full complement of accessories. This 3 phase load center has 12 spaces and 12 circuits. This system provides 100A convertible main lugs in a NEMA 1 enclosure. This product is CSA and UL rated.
Features
- Engineered for 3-phase, 4-wire electrical systems, this 125-amp maximum capacity load center features convertible main lugs to adapt to your specific building requirements. Offering 12 full spaces (and up to 24 circuits), it serves as the perfect high-efficiency sub-panel for safely distributing 120/240V power to retail HVAC units, commercial lighting banks, or light industrial machinery.
- Built with shielded, premium tin-plated copper bus bars, this Square D QO panel guarantees superior electrical conductivity and exceptional thermal stability compared to standard aluminum alternatives. This rugged, oxidation-resistant construction virtually eliminates the risk of loose connections and heat degradation, ensuring uninterrupted power flow and minimizing expensive maintenance call-backs for facility electricians.
- Housed in a heavy-duty, welded sheet steel NEMA 1 enclosure, this indoor-rated panel provides absolute protection against dust and accidental live contact. Its electrician-friendly design features optimized, straight-in main wiring and strategically placed knockouts, dramatically reducing installation labor time and making complex commercial panel upgrades clean and straightforward.
- Fully cULus Listed and CSA Certified, this component meets the most rigorous North American National Electrical Code (NEC) standards for commercial power distribution. It is specifically designed for seamless, snap-in integration with industry-leading Square D QO circuit breakers—including AFCI, GFCI, and surge protectors—guaranteeing your commercial installation remains heavily protected and fully liability-compliant.
