The SQDFPNF484L4 is a complete Square D NF-Series panelboard rated at 400A, 347/600V with 84 circuits (MLO — Main Lug Only), designed for commercial power distribution in Canadian three-phase wye systems. As an MLO panel, it requires a separately installed upstream main breaker or disconnect feeding the bus. The NF series accepts Square D NF-frame branch breakers; it is a commercial/industrial panelboard and is not interchangeable with Square D QO or Homeline residential loadcentres.
Branch breaker compatibility and feeder sizing details can vary by installation — send us your project specs and we'll confirm the right breakers and accessories for this panel.
The NF-series panelboard accepts Square D NF-frame breakers rated for 347/600V. These are commercial-grade, bolt-in breakers distinct from residential QO or Homeline types. Contact our team with your circuit amperage and pole requirements and we'll identify the correct NF breakers for your application.
MLO stands for Main Lug Only, meaning this panel does not include a built-in main breaker. You will need an upstream main breaker, fusible disconnect, or service entrance device rated for 400A/347-600V installed ahead of this panel. Your electrical contractor or engineer can confirm the correct upstream protection for your system.
