The H2V performance class means it interrupts faults up to 100 kA at 415 V AC, which puts it in the high-breaking-capacity tier for industrial distribution where fault currents are stiff and coordination with downstream gear matters. Drawout mounting means the breaker chassis stays bolted to the switchgear, and the moving portion slides out for inspection or swap without pulling cables. That cuts downtime on a line-down event — you rack it out, slide in a spare, and get back to making clinker. The 441 mm width and 439 mm height fit standard MasterPact MTZ2 cubicle cutouts; depth is 403 mm, which you need to account for in the enclosure depth before you spec the gland plate. ## Breaking capacity — the number that governs coordination The Ics (service breaking capacity) matches at 100 kA — meaning after a fault at full rating the breaker can be reclosed and carry rated current without immediate replacement. That is Category B selectivity, so it coordinates with downstream breakers: a fault on a branch trips the branch breaker, not this main, keeping the rest of the plant live. For a cement plant where losing the main kills the kiln feed, that selectivity keeps the raw mill running while a downstream fault clears. Short-time withstand (Icw) is 100 kA for 0.5 s and 1 s, and 75 kA for 3 s. That tells you the breaker holds closed under fault current long enough for downstream devices to clear — essential for selective coordination. The making capacity (Icm) is 220 kA at 440 V AC, which covers the worst-case asymmetrical peak when closing into a bolted fault. ## What the standards tell you about where it goes Compliant with EN/IEC 60947-1 (general rules), EN/IEC 60947-2 (circuit-breakers), and Annex H for EMC. Also meets IEC 61557-12 for power metering if equipped with the optional metering module. Altitude derating starts above 2000 m — fine for most cement plants unless you are at a highland site.","metaTitle":"Schneider Electric LV846171 MasterPact MTZ2 1000A 3P Drawout","metaDescription":"Schneider Electric LV846171 MasterPact MTZ2 circuit breaker, 1000 A rated at 40 °C, 100 kA breaking capacity at 440 V AC, 3-pole drawout.
