Schneider Electric's Square D 3P4W I-Line Panelboard Assembly is an 800 A, 600 V AC main-lug-only (MLO) panelboard with 42 circuit positions for a three-phase, four-wire system. This I-Line distribution panel is intended for service entrance or downstream distribution in commercial and industrial facilities, using the I-Line bus system and compatible Square D I-Line breakers to protect and control loads. With its 42-circuit capacity and 3P4W arrangement, it supports high-capacity distribution while keeping the main disconnect upstream.
