It carries UL 489 listings at 200 kA Icu at 240 V AC, 150 kA Icu at 480 V AC, and 100 kA Icu at 600 V AC — the Icu values tell you the maximum fault current it can safely interrupt at each voltage level, which governs the available fault current your system can tolerate upstream. The drawout cradle means the breaker can be racked out for maintenance or replacement without disturbing line-side connections, standard for switchgear lineups. The integral instantaneous protection is set at 49.5 to 55.5 kA, meaning the breaker clears bolted faults above that threshold without intentional delay, which is typical for the LF (low-energy) breaking capacity variant. ## Integration notes Drawout mounting on base plate rails. The unit occupies a 17.5 in wide by 17.3 in tall by 16.8 in deep footprint (444.3 x 438.8 x 426.8 mm). Connection pitch is 4.5 in (115 mm) between phases. Mechanical durability is rated at 10,000 cycles per ANSI C37.50; electrical durability at 1,000 cycles under load — the gap reflects contact wear from arc interruption. Maximum breaking time is 9 ms, closing response time 70 ms, which matters for arc-flash incident energy calculations.","metaTitle":"Schneider LV839163 MasterPact MTZ2 800A 3P Drawout, 200kA Ic","metaDescription":"Obsolete Schneider LV839163 MasterPact MTZ2 circuit breaker, 800A, 3-pole, drawout, 200kA Icu at 240V UL 489.
