The LV846325 is a Schneider Electric MasterPact MTZ2 40HH switch disconnector rated for 4000 A at 440 V AC, built for distribution duty in heavy industrial environments. The drawout chassis mount means you pull the cassette for inspection or swap without killing the bus—critical in a mine or mill where downtime costs by the minute. It is an isolation switch (suitability for isolation per EN/IEC 60947-3) with a visible contact position indicator, so a locked-out tag-out is verifiable at the panel door. Four poles, push-button control, and a 12 kV impulse withstand voltage give it the clearance for 1000 V AC insulation-rated circuits.
Drawout mounting on a chassis support; connection pitch is 115 mm between phases. The 556 mm width by 439 mm height by 403 mm depth footprint fits standard MasterPact switchgear cubicles.
Rated for AC-23A and AC-3 utilisation categories—AC-23A covers occasional switching of motors and other highly inductive loads (5000 cycles electrical durability at 440 V), while AC-3 covers routine motor starting. The 75 kA Icw for 3 seconds (100 kA for 1 second) gives protection coordination flexibility with downstream breakers.
