The Schneider Electric LV846195 is a MasterPact MTZ2 drawout circuit breaker, 4-pole, rated 2500 A at 40 °C with a H2V performance class delivering 100 kA breaking capacity at 415 V AC. It sits in the MasterPacT range, designed for power distribution protection in commercial and industrial switchboards where you need Category B selectivity — meaning it coordinates with downstream breakers to isolate only the faulted circuit, keeping the rest of the plant live.
The Icw of 100 kA for 1 second gives you headroom for short-time delay coordination with downstream feeders. Maximum breaking time is 25 ms, closing response 70 ms, so it's fast enough for arc-flash mitigation schemes but deliberate enough for zone-selective interlocking.
Drawout mounting on rails or base plate. Dimensions: 556 mm wide, 439 mm high, 403 mm deep. Connection pitch is 115 mm. Upside and downside connections both offer front or rear termination — gives panel builders flexibility for cable entry and busbar layout. IP30 protection means it's for indoor switchgear, not washdown areas.
Also complies with IEC 61557-12 for measuring equipment.
