It carries a Category B selectivity classification (EN/IEC 60947-2), meaning it can discriminate with downstream breakers to keep a fault isolated to the smallest section of the installation — critical for maintaining uptime on a production line or critical process. The H10 performance grade delivers a 50 kA Ics (service breaking capacity) at 1150 V AC, 50/60 Hz, with a corresponding Icm (making capacity) of 105 kA at the same voltage. That 50 kA Ics is the breaker's ability to clear a fault and be immediately reclosed — not a one-shot sacrificial rating. The Icw (short-time withstand) is 50 kA for up to 3 seconds, which gives downstream protection devices time to clear a fault before the main breaker trips, supporting selective coordination in a multi-tier distribution system. ## Physical integration — fixed mount, rear connection, 537 mm wide Fixed-mounted on rails or a base plate, with rear connection on both the line and load sides. The 537 mm width, 352 mm height, and 300 mm depth define the panel cutout and enclosure size needed — this is a large-frame breaker that requires a dedicated compartment in the switchboard, not a DIN-rail unit. Connection pitch is 115 mm, matching standard busbar or cable lug spacing for 3200 A class terminations. Neutral position is left, 4-pole (3 phases + neutral switched). Rated operational voltage is 1150 V AC — this is a 1000 V-class breaker, common in heavy industrial and mining installations where 690 V or 1000 V distribution is used. ## Durability and operating conditions Mechanical durability is 20,000 cycles with periodic preventive maintenance; electrical durability is 500 cycles at 1150 V AC, 50/60 Hz per EN/IEC 60947-2. Maximum breaking time is 25 ms, closing response time is 70 ms. Operating altitude is 0–2000 m without derating; above 2000 m up to 5000 m requires derating per the manufacturer's guidelines. The breaker is supplied without a control unit — the Micrologic trip unit is ordered separately or as part of a configured assembly, so verify the trip unit type (A, E, P, or H) when specifying the complete breaker.","metaTitle":"Schneider LV846556 MasterPact MTZ2 3200A, 50kA at 1150V","metaDescription":"LV846556 MasterPact MTZ2 fixed circuit breaker, 3200A rated, 50kA Ics at 1150V AC, 4P, rear connection, current lifecycle, sourced to order.

The LV846556 is the 3200 A, H10 (50 kA at 1150 V), 4P fixed version. A lower-current variant would share the same physical footprint and connection pitch but require a different order code and trip-unit configuration.
