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 24 spaces and 24 circuits. This system provides a 100A convertible main breaker in a NEMA 1 enclosure. This product is UL rated.

Features

The QO324MB100 comes pre-equipped with a 100A factory-installed main breaker, serving as a dedicated service disconnect for your electrical system. This eliminates the need for separate upstream disconnects in many applications, simplifying your installation and ensuring rapid power shut-off for improved job site safety.
Designed specifically for 208Y/120V AC or 240/120V AC 3-phase systems, this load center provides the balanced power distribution necessary for light commercial machinery and professional HVAC units. It allows for the efficient operation of 3-pole breakers, ensuring your facility can handle high-torque motors and sensitive electronics without the phase-loss risks of single-phase setups.
This QO Load Center features a rugged, cold-rolled steel NEMA 1 enclosure designed specifically for indoor environments like garages, basements, or utility rooms. The neutral gray baked-enamel finish provides superior corrosion resistance, ensuring the housing remains professional and intact while protecting your critical electrical distribution components for decades.
Featuring the industry-leading shielded bus bar and "QO" plug-on mounting, this panel allows for the fastest breaker installation in the industry. The lack of screw-on connections for branch breakers not only speeds up the "rough-in" phase but also provides a more secure, vibration-resistant electrical contact that reduces the risk of overheating and premature component failure.
