It carries a 630 A rated current at 40 °C across four poles, with an H3 performance class delivering 66 kA breaking capacity at 415 V AC. That 66 kA rating means it clears high-fault currents on a 415 V industrial feeder without upstream devices needing to trip — a Category B selectivity device that coordinates with downstream breakers to isolate only the faulted branch. Rated operational voltage (Ue) is 690 V AC 50/60 Hz, with insulation voltage (Ui) at 1000 V AC and impulse withstand (Uimp) at 12 kV — this breaker handles standard 400/480 V distribution and steps up to 690 V for mining or marine gear. Short-time withstand (Icw) holds 30 kA for 3 seconds, critical for selective coordination with downstream devices. Making capacity (Icm) hits 145 kA at 440 V AC, so it closes against a bolted fault without welding contacts. ## Deployment context This is a drawout breaker — the chassis stays wired to the bus, the breaker cassette slides in and out for safe swap without disturbing connections. Mounts on rails or a base plate inside a switchgear lineup. Front and rear connection options give flexibility for cable or busbar entry. IP30 protection suits enclosed switchgear; not for open washdown areas.","metaTitle":"Schneider Electric LV846457 MasterPact MTZ1 630A 4P Drawout","metaDescription":"Schneider Electric LV846457 MasterPact MTZ1 drawout circuit breaker. 630 A rated current, 4 poles, H3 66 kA breaking capacity at 415 V AC.
