The Schneider Electric LV846314 is a MasterPact MTZ2 32 HH switch-disconnector rated for 3200 A continuous at 440 V AC, three poles, fixed-mount chassis.
At 440 V AC the Icu is 100 kA, and the Ics is also 100 kA — a 100% Ics/Icu ratio. That means after clearing a fault at full rating the switch can be immediately reclosed without inspection or parts replacement. For a site engineer coordinating with downstream breakers, the Icw is 75 kA for 3 s or 100 kA for 1 s, which gives the upstream relay enough time to discriminate without letting the arc through.
Fixed-mount chassis, 422 mm wide by 352 mm high by 300 mm deep. IP30 front face protection; install in a cabinet with at least IP3X enclosure for the live parts.
Duty and isolation
Utilisation categories AC-23A and AC-3 cover switching of motor loads and mixed resistive-inductive loads.
