This is a 3-pole drawout unit rated for 5000 A at 40 °C, meaning it handles full continuous current in distribution switchgear without forced cooling. The 100 kA Icu at 254 V AC and 85 kA Icu at 635 V AC (with external relay, per ANSI C37.50) tell you the interrupting capacity for fault clearing — a key selectivity coordination figure for the main breaker position in a low-voltage switchboard. The drawout mounting means the breaker chassis slides into a cradle with disconnect positions for test and isolated — no need to unbolt line/load conductors for maintenance. The chassis support is a fixed frame; the moving portion is the breaker itself. Connection pitch is 9.06 in (230 mm) between phase centers, which dictates bus bar take-off spacing in the switchgear lineup. Push-button control on the front fascia handles local open/close operations. The [Icw] rated short-time withstand current of 85 kA for 1.5 seconds confirms this breaker can carry fault current through the delayed trip coordination window — essential for zone-selective interlocking in large distribution systems. Physical dimensions: the unit measures 31.07 in (789.1 mm) wide, 18.8 in (478.1 mm) high, and 16.8 in (426.8 mm) deep. These are the overall envelope dimensions for the drawout cradle assembly — verify the switchgear cell opening matches before specifying.","metaTitle":"Schneider Electric LV839314 Masterpact MTZ3 50 HF, 5000A Dra","metaDescription":"Schneider Electric LV839314 Masterpact MTZ3 50 HF switch disconnector, 5000A rated operational current, 100kA Icu at 254V AC, drawout, 3P.
