It's a Category B breaker, meaning it's fully rated for selectivity in power distribution protection schemes where you need coordinated fault isolation downstream. This is a bare breaker — no control unit fitted. You'll add the trip unit separately. That's typical for a spec'd-in breaker where the protection settings are defined at the panel design stage, not a shelf-stocked unit. Rated operational voltage is 690 V AC 50/60 Hz, with an insulation voltage of 1000 V AC — so it lives comfortably in 400 V and 480 V distribution panels and still has headroom for 690 V industrial supplies. The impulse withstand voltage of 12 kV tells you it handles transient overvoltages in an industrial environment without flashover. Service breaking capacity (Ics) is 66 kA across the board — 220/415 V, 440 V, 500/525 V, and 660/690 V AC. That's a uniform 100% rating, not a derated service value. Short-time withstand (Icw) is 66 kA for 0.5 s and 1 s, dropping to 36 kA at 3 s — essential data for selective coordination studies with downstream breakers. Mechanical durability is 25,000 cycles with periodic preventive maintenance; electrical durability is 10,000 cycles at 440 V and 690 V AC under EN/IEC 60947-2, and 6,000 cycles under AC-3 motor-switching duty per EN/IEC 60947-3. For a 1000 A frame, that's solid — this breaker is built for a main or large feeder position, not frequent switching. Power dissipation is 70 W at rated current. Factor it into your thermal calculation, especially if the panel is IP-rated and sealed. Fixed mounting on rails or a base plate. Connection pitch is 115 mm. Both upside and downside connections accept front or rear terminations — gives you flexibility in busbar or cable routing. Neutral is on the right. Dimensions: 537 mm wide, 352 mm high, 300 mm deep. That's a substantial footprint — plan the panel layout accordingly. IP30 protection per EN 60529 — basic finger protection, not washdown. This lives inside a switchboard or enclosure, not in a wet environment. Altitude rating: 0–2000 m no derating, 2000–5000 m with derating. That covers most installations except high-altitude mining or mountain-top sites above 5000 m.","metaTitle":"LV848184 MasterPact MTZ2 4P 1000A Fixed Circuit Breaker, H1","metaDescription":"Schneider Electric LV848184 MasterPact MTZ2 4P 1000A fixed circuit breaker, H1 performance (66 kA at 415 V AC).
