It's a 4-pole fixed-mount unit with right-side neutral, built to EN/IEC 60947-3 for switch-disconnector duty, and certified for isolation (visible contact position indicator confirms the gap). ## Duty cycle and endurance Mechanical endurance is 15,000 cycles with periodic preventive maintenance per EN/IEC 60947-3. Electrical durability under AC-23A (motor switching, high inrush) is 5,000 cycles at 440 V — that's the contact wear life for frequent motor or transformer switching. For distribution-only duty (AC-21A/AC-22A) the electrical life will be longer, but the catalog figure is the worst-case rating. The short-time withstand (Icw) is 75 kA for 3 seconds or 100 kA for 1 second, which governs selectivity coordination with downstream breakers during a fault hold-off period. ## Installation environment Fixed-mount chassis, 537 mm wide × 352 mm high × 300 mm deep — panel cutout and busbar pitch (115 mm connection pitch) need to match the existing MasterPact MTZ2 footprint.","metaTitle":"Schneider Electric LV846343 MasterPact MTZ2 25HH Switch Disc","metaDescription":"LV846343 MasterPact MTZ2 25HH switch disconnector, 2500 A rated current, 100 kA breaking capacity at 440 V AC, 4P fixed, active production.
