The LV846318 is a MasterPact MTZ2 20HH switch disconnector rated for 2000 A continuous current at 440 V AC — that's the full-load current it carries without exceeding temperature rise limits, sized for a main feeder or a large distribution bus. The drawout chassis lets you rack the unit out for inspection or swap without de-energizing the bus, which cuts downtime on a critical feeder.
Drawout integration and isolation duty
Mounts on a dedicated chassis with a 115 mm connection pitch — the drawout mechanism engages the primary disconnects as you rack in, and the contact position indicator confirms the blade state visually. Rated for isolation per EN/IEC 60947-3, so it provides a visible-break-equivalent gap when racked to the test or disconnected position.
