That 2500 A frame is the backbone of a main or tie breaker in a low-voltage switchboard — it carries the full load of a large distribution transformer or a high-density industrial feeder without forced cooling. That is Category B selectivity, so downstream breakers can be coordinated to isolate only the faulted branch while the main stays closed on a through-fault. Short-time withstand (Icw) is 100 kA for 1 second. Impulse withstand (Uimp) is 12 kV; insulation voltage (Ui) is 1000 V. Drawout mounting means the breaker cassette stays wired to the bus; the breaker itself racks out for maintenance or replacement without disturbing the power connections. Mounting support is rails or base plate — standard for switchgear cubicle integration. ## Sourcing and lifecycle — current production, no obsolescence concern Compliance documentation is covered by the standards listed: EN/IEC 60947-1, EN/IEC 60947-2, EN/IEC 60947-2 Annex H, and IEC 61557-12. These are the governing standards for low-voltage switchgear and controlgear assemblies, covering the breaker's design, testing, and isolation suitability. ## Integration — what fits in the cubicle Footprint is 441 mm wide by 439 mm high by 403 mm deep — a standard drawout cassette size for the MTZ2 frame. Connection pitch is 115 mm between phase centers, matching the bus-bar drilling pattern on most low-voltage switchgear lineups. Upside and downside connections are both available in front or rear configurations — the same breaker can be ordered for either cable-entry topology without a hardware change. Power dissipation at rated current is 600 W — account for that heat in the cubicle ventilation budget. Altitude derating starts above 2000 m — no derating needed for most industrial sites. ## Durability and response — what the cycle counts mean for maintenance planning Mechanical durability is 15,000 cycles with periodic preventive maintenance — that is the mechanism life before a major overhaul. Electrical durability is 5000 cycles at rated current at 440 V AC under EN/IEC 60947-2 AC-23A duty, and 6000 cycles under EN/IEC 60947-3 AC-3 motor-switching duty. For a main breaker that operates a few times a year, that is decades of service. Maximum breaking time is 25 ms; maximum closing response time is 70 ms. These are the mechanical operating times — the actual arc-extinction time is shorter and depends on the fault current level.","metaTitle":"Schneider Electric LV846175 MasterPact MTZ2 2500 A Circuit B","metaDescription":"Schneider Electric LV846175 MasterPact MTZ2 drawout circuit breaker, 2500 A rated current, 100 kA Icu at 440 V AC.
