It sits in the H10 performance tier, meaning it clears 50 kA faults without upstream coordination issues — the 50 kA Ics equals the Icu, so it can reclose after a fault at full rating, which matters for critical-feed continuity. It's a Category B breaker per IEC 60947-2, designed for selective coordination with downstream devices — the short-time withstand (Icw) of 50 kA for 1 s lets it ride through a fault long enough for a downstream breaker to clear, keeping the main bus live. Rated at 2000 A continuous, with a 1250 V insulation voltage (Ui) and 1150 V operational voltage (Ue). The 12 kV impulse withstand (Uimp) covers surge coordination in industrial distribution panels. That's typical for a large-frame power breaker — it's not intended for frequent switching, but for protection and isolation. The 250 W power dissipation at rated current matters for panel cooling calculations. Fixed-mount on rails or a base plate, with rear connections both top and bottom — that's the standard for switchboard or MCC integration where you want bus-bar connections behind the breaker. The 115 mm connection pitch matches common bus-bar drilling patterns. IP30 enclosure protection means it's for indoor, dry locations; no washdown rating. Push-button control, no electronic control unit — this is a basic thermal-magnetic or micrologic trip unit carrier (the sensor rating covers 1000 A to 2000 A, so the trip unit is field-selectable). The 25 ms maximum break time and 70 ms max closing time are standard for this class. ## Compliance and isolation Certified to EN/IEC 60947-1, -2, and Annex H for selectivity, plus IEC 61557-12 for performance. Suitability for isolation is confirmed — it can be used as a disconnecting means per code. Pollution degree 3 (industrial environment) per IEC 60947-1. Operating altitude to 2000 m without derating, to 5000 m with derating.","metaTitle":"LV846544 MasterPact MTZ2 2000A 3P 50kA @1150V AC Circuit Bre","metaDescription":"LV846544 MasterPact MTZ2 3P fixed circuit breaker, 2000 A rated at 40 °C, 50 kA Icu/Ics at 1150 V AC.
