It's built for power distribution protection — main or tie breaker in a switchboard, protecting transformers, busbars, or large feeders. Category B selectivity means it coordinates with downstream breakers to isolate only the faulted branch. ## Drawout mounting and panel fit Drawout mounting means the breaker chassis stays wired to the bus; the moving portion slides out for maintenance or swap without pulling the whole switchboard apart. Mounting support is rails or base plate — standard for switchgear cubicles. The 441 mm width, 439 mm height, and 403 mm depth fit typical low-voltage switchgear compartments; connection pitch is 115 mm. Upside and downside connections accept front or rear terminations, so it adapts to existing busbar runs or cable ladders. The Icw short-time withstand of 100 kA for 1 s (75 kA for 3 s) is what makes Category B selectivity work — it rides through a downstream fault long enough for the branch breaker to clear, then opens only if the fault persists. Making capacity Icm is 220 kA at 440 V, which covers the asymmetric peak on the first half-cycle. For coordination studies, the 25 ms maximum breaking time and 70 ms maximum closing response time are the numbers to plug into your time-current curves. The MasterPact MTZ2 platform is Schneider's active drawout breaker line, so firmware revisions, spare parts, and Micrologic trip unit options remain available. If you need a different trip unit or a fixed-mount version, the MTZ2 family has those variants, but this specific order code is the 3P drawout, 2000 A, H2V, without control unit. ## What the standards and environmental ratings cover The LV846174 carries EN/IEC 60947-1, -2, and Annex H (for selectivity under earth-fault conditions), plus IEC 61557-12 for performance measurement and monitoring. Operating altitude is 0–2000 m without derating, 2000–5000 m with derating. IP30 protection means tools or fingers won't reach live parts, but it's not sealed against water — install in a cabinet. The 470 W power dissipation at rated current matters for ventilation sizing in the enclosure.","metaTitle":"LV846174 MasterPact MTZ2 3P Drawout, 2000 A, 100 kA","metaDescription":"LV846174 MasterPact MTZ2 circuit breaker, 3P drawout, 2000 A rated at 40 °C, 100 kA breaking at 440 V AC.
