That 2000 A continuous current handles the main feed of a large distribution board or a high-load industrial bus. The H2V performance grade delivers 100 kA ultimate breaking capacity (Icu) at 440 V AC — enough to clear a bolted fault on a transformer secondary without upstream coordination issues. Category B selectivity means it holds full discrimination with downstream breakers, so a fault on a branch won't drop the main. The short-time withstand (Icw) is 100 kA for 0.5 s and 1 s, and 75 kA for 3 s — that's the thermal and dynamic stress the breaker can carry during a delayed trip. For selective coordination schemes where the main breaker waits for a downstream device to clear, this Icw rating is the number that governs. The making capacity (Icm) of 220 kA at 440 V AC confirms the contacts can close into a fault without welding. Mounting is fixed on rails or a base plate, with front or rear connections on both the line and load sides. The 422 mm width, 352 mm height, and 300 mm depth fit a standard switchboard cubicle — plan for the 115 mm connection pitch when laying out busbars. IP30 protection suits indoor panel installation; no additional enclosure needed for dust or drip protection. ## Standards and compliance — what the approvals cover The breaker complies with EN/IEC 60947-1 (general rules), EN/IEC 60947-2 (circuit breakers), and EN/IEC 60947-2 Annex H (selective breakers). It also meets IEC 61557-12 for performance measurement in power distribution. ## Durability and thermal — cycles and dissipation Mechanical durability is 15,000 cycles with periodic preventive maintenance. Electrical durability under AC-23A (frequent switching of motor loads) is 8,000 cycles at 440 V AC and rated current; under AC-3 (direct switching of motors) it is 6,000 cycles. Power dissipation at rated current is 250 W — factor that into cabinet ventilation calculations.","metaTitle":"Schneider Electric MasterPact MTZ2 LV846164, 2000 A, 100 kA","metaDescription":"LV846164 MasterPact MTZ2 3P fixed circuit breaker, 2000 A, 100 kA breaking capacity at 440 V AC.
