Panelboard Interior 400 A 277/480VAC MPN:NF442L4

These Square D NF main lug panel interiors distribute power downstream from main breakers. They're 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. They're used with bolt-on branch circuit breakers and top and bottom feed breakers to protect circuits from overcurrents. These interiors are used as part of a complete panelboard system and can be customized to meet different needs. They're used in residential, commercial, and industrial applications.
