Panelboard Interior 400 A 240VAC/48VDC MPN:NQ442L4C

These Square D NQ main lug panel interiors distribute power downstream from main breakers and are used with QO plug-in and QOB bolt-on circuit breakers to protect circuits from overcurrents. These interiors are used when all the circuit slots in the main breaker load center are full or when a remote panel is desired. They can be converted to a main breaker load center with a required adapter kit and main circuit breaker, so they can be used to distribute the main supply of power if needed. These interiors are used as part of a complete panelboard system and can be customized to meet different needs. They can be used for lighting and appliance protection in commercial and industrial applications.
