The Schneider Electric Masterpact MTZ3 60 HC (LV839094) is a fixed-mounted, three-pole switch disconnector rated for 6000 A at 104 °F (40 °C) — that is the continuous current it carries without derating in a typical distribution panel.
Deployment context
Fixed mounting means this unit bolts directly into a switchboard or MCC lineup — no draw-out cradle. The 30.2 in (767 mm) width and 13.9 in (352.2 mm) height fit standard ANSI switchgear cubicle openings; the 11.7 in (297.7 mm) depth leaves room for rear cable lugs or bus connections. Push-button control on the front cover gives local open/close without opening the door.
