The SQDFPNQ430L2 is a Square D NQ Series panelboard rated at 225A, 120/208V 3-phase 4-wire with 30 circuits and a Main Lugs Only (MLO) configuration, meaning it requires an upstream overcurrent protective device. The NQ Series is a commercial/industrial panelboard intended for mounting in switchboards, distribution systems, or as a sub-panel fed from a larger main breaker or disconnect — it is not a residential loadcentre. It accepts Square D NQ-compatible branch breakers and accessories designed for this series.
If you need to confirm branch breaker compatibility, interior configurations, or upstream feed requirements for your specific installation, send us your project details and we'll confirm the right fit.
MLO stands for Main Lugs Only — the SQDFPNQ430L2 has no built-in main breaker. You must provide an upstream overcurrent protective device (such as a main breaker or fusible disconnect) sized to protect the 225A bus. This is common in commercial sub-panel installations where the main disconnect is located in a distribution board upstream.
The Square D NQ Series is a commercial/industrial panelboard, not a residential loadcentre. It is designed for use in commercial buildings, industrial facilities, and multi-unit developments where a robust, 3-phase 120/208V distribution solution is required. It is not interchangeable with Square D QO or Homeline residential loadcentres.
