It's built for power distribution protection in industrial switchgear, with a Category B selectivity rating per IEC 60947-2 — meaning it's designed to discriminate faults downstream and keep upstream feeders live. Both ratings are verified at 1150 V, 50/60 Hz. The 50 kA Icu (ultimate breaking capacity) and 50 kA Ics (service breaking capacity) are equal here, so the breaker can clear a fault at its full rating and still be usable afterward. The Icw short-time withstand of 50 kA for 3 seconds means it coordinates with downstream breakers that take time to clear; the 25 ms maximum break time limits arc energy. Insulation voltage Ui is 1250 V AC, impulse withstand Uimp is 12 kV — both confirm the breaker's clearance for 1150 V systems with transient overvoltages. This is a fixed-mount breaker — no draw-out cradle. It bolts to a base plate or rails (mounting support per), with rear connections on both the line and load sides (upside and downside connection: Rear). The 422 mm width, 352 mm height, and 300 mm depth define the panel cutout and enclosure depth needed; the 115 mm connection pitch matches standard busbar or cable lug spacing. IP30 protection means it's suitable for enclosed switchgear where tools are needed to access live parts — not for washdown areas. Operating altitude is 0–2000 m without derating; above that, up to 5000 m, derate per the manufacturer's curve.","metaTitle":"LV846547 MasterPact MTZ2 3P 4000A Circuit Breaker, 50 kA Icu","metaDescription":"Schneider Electric LV846547 MasterPact MTZ2 fixed circuit breaker, 3P, 4000 A rated current, 50 kA Icu at 1150 V AC.
