You pair it with the trip platform separately. Breaking capacity hits 100 kA Icu at 254 VAC and 85 kA Icu at 635 VAC per ANSI C37.50, so it handles high-fault utility feeds or large transformer secondaries where the available fault current is substantial. The 4-pole (4P) configuration covers three-phase plus neutral, with neutral on the left. Drawout mounting means the cradle stays wired in the switchgear; the breaker slides out for maintenance or replacement without disturbing the bus connections. ## Integration notes Drawout cradle requires base plate rails for mounting (listed as mounting support). The unit is 40.5 in wide, 18.8 in tall, 16.8 in deep — verify your switchgear cell opening and racking mechanism clearance before specifying. Connection pitch is 9.06 in (230 mm). Mechanical durability is 12,500 cycles; electrical durability is 2,800 cycles per ANSI C37.50, which governs the maintenance interval for the application.","metaTitle":"LV839033 MasterPact MTZ3 5000 A 4P Drawout, 100 kA Icu","metaDescription":"Schneider Electric MasterPact MTZ3 LV839033 circuit breaker, 5000 A rated, 4-pole drawout, 100 kA Icu at 254 VAC.
