The MGP1604NATX is a Schneider Electric PowerPact 4 switch disconnector, rated 160 A continuous on a 4-pole (4P) frame. It is designed for isolation duty in panelboard applications up to 630 A bus rating, with a utilisation category of AC-22A/AC-23A and DC-22A/DC-23A — meaning it handles mixed resistive and moderately inductive loads, plus occasional motor switching, but not the high inrush of dedicated motor-starter duty. The 415 V AC rated operational voltage (Ue) and 800 V AC rated insulation voltage (Ui) suit it for standard low-voltage distribution in 400 V class systems.
The 160 A rating is the continuous current at 40 °C ambient; the switch carries a short-time withstand (Icw) of 2500 A for 1 s and a making capacity (Icm) of 3.6 kA peak, so it can close onto a fault of that magnitude once. The IK07 impact rating confirms it survives a 2 J hammer blow typical of panel-door handling. Pollution degree 3 per EN/IEC 60664-1 means it is rated for conductive pollution in industrial environments, so no additional conformal coating is required inside a standard IP40 enclosure.
Integration Notes
Mounts to a backplate via the 161 mm height and 140 mm width footprint — no DIN-rail clip, so plan for drilled-and-tapped or through-hole fixing. Top-entry connection simplifies bus-bar routing in panelboard builds but means cables enter from above; verify clearance above the switch for bending radius. The toggle control provides a visible break and a contact-position indicator, meeting the isolation requirements of BS EN 60947-3 for lockout/tagout procedures.
