That 1600 A frame covers large secondary transformers, main feeders, or generator incomers in ANSI-distribution gear. The L1F breaking capacity code delivers 200 kA Icu at 254 V AC and 130 kA Icu at 635 V AC per ANSI C37.50 — meaning it can safely interrupt fault currents up to that level without upstream cascading. Short-time withstand (Icw) is 22 kA for 0.5 s, which governs coordination with downstream breakers during a delayed trip. Mechanical endurance is 12,500 cycles, electrical endurance 2,800 cycles under ANSI C37.50. The integral instantaneous protection is set at 49.5 to 55.5 kA — a fixed magnetic range for bolted-fault clearing. Maximum break time is 9 ms, closing response 70 ms. Drawout mounting (4.5-inch connection pitch) means the breaker slides onto base-plate rails for racking in and out without disturbing power wiring — standard for switchgear where isolation for maintenance is required.","metaTitle":"Schneider LV839099 MasterPact MTZ2 1600A 3P Drawout, 200kA I","metaDescription":"Schneider Electric LV839099 MasterPact MTZ2 circuit breaker, 1600A rated, 3-pole drawout, 200 kA Icu at 254 VAC.
