Schneider Electric LV846323 is a MasterPact MTZ2 32 HH switch-disconnector rated for 3200 A at 440 V AC, 50/60 Hz, with 4 poles in a drawout chassis mount.
Breaking capacity and duty ratings
The short-time withstand (Icw) is 75 kA for 3 s, or 100 kA for 1 s, covering delayed coordination with downstream breakers. Utilisation categories AC-23A and AC-3 confirm it handles motor loads and mixed resistive-inductive switching, with an electrical durability of 5000 cycles at 440 V under AC-23A.
Drawout mounting on a chassis support allows the switch-disconnector to be racked in and out for maintenance without disturbing the bus connections. The 115 mm connection pitch matches standard MasterPact drawout cradle dimensions. IP30 protection suits enclosed switchgear — not exposed washdown areas.
