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 20 spaces and 20 circuits. This system provides 125A convertible main lugs in a NEMA 1 enclosure. This product is CSA rated.
Features
- Designed with a rugged, cold-rolled steel NEMA 1 enclosure, this load center is optimized for surface-mount installation in dry, indoor environments like utility rooms, basements, or commercial closets. The compact 3-phase footprint provides a professional-grade power distribution hub that protects internal components from dust and debris while maintaining a clean, low-profile appearance.
- Rated for 120/240V AC three-phase systems, this 20-amp main lug load center is specifically engineered to serve as a high-efficiency sub-panel. Because it does not feature a main breaker, it allows for a direct, cost-effective connection to a larger upstream distribution system, making it the ideal solution for adding dedicated 3-phase power to specific equipment zones or small commercial workspaces.
- This load center is built exclusively for Schneider Electric s industry-leading QO "Plug-On" circuit breakers, which are widely recognized as the fastest and most secure in the industry. The shielded bus bar design helps prevent accidental contact with energized parts, while the high-performance copper bus construction ensures maximum conductivity and heat dissipation for your critical electrical circuits.
- Featuring a fully shielded bus bar and UL Listed certification, this load center provides an extra layer of protection against accidental arc flashes and electrical faults. By meeting the most stringent National Electrical Code (NEC) requirements, this factory-tested unit ensures your commercial property stays compliant with local safety regulations while protecting sensitive machinery and personnel from electrical hazards.
