Square D Q0N430M200 Panelboard Interior Assembly

Square D QO430M200 Panelboard Interior Assembly is a 200-amp, 240-volt interior kit for Square D QO-series panelboards, engineered to host three-phase distribution and accept compatible QO circuit breakers within a durable, factory-assembled bus and mounting framework. This interior assembly forms the core of a panelboard for three-phase service, providing the bus structure, mounting rails, neutral/grounding provisions, and enclosure interface needed to tailor the panel to the project’s circuit count, protection requirements, and installation layout. Manufactured by Square D (Schneider Electric), the QO430M200 is designed for commercial or light-industrial electrical distribution where a 200 A service is required and where standard QO breakers and accessories are used to complete the protection and coordination of the system. Use with compatible QO breakers to finalize the protection scheme, ensuring code compliance, accurate labeling, and straightforward serviceability within a three-phase distribution network; this interior is typically paired with a matching QO enclosure to form a complete panelboard solution for HVAC, lighting, and other branch-circuit applications.
