Rated operational current of 5000 A means this breaker handles the main incoming feed for a large industrial distribution panel or a high-current bus riser — not a branch circuit, not a motor load center. The 3-pole form serves three-phase 50/60 Hz AC networks. Breaking capacity reaches 200 kA Icu at 240 V AC, 150 kA Icu at 480 V AC, and 100 kA Icu at 600 V AC per UL 489 — that is the fault current it can safely interrupt without welding contacts or rupturing the arc chamber. For a 5000 A frame, those numbers mean it can sit at the service entrance behind a transformer rated for high available fault current. ## Drawout mounting and panel fit Drawout mounting means the breaker mechanism slides into a fixed cradle on the chassis — you can rack it out for maintenance or replacement without disconnecting the main bus bars. The chassis mount is specified for a 31.07 in (789.1 mm) wide by 18.8 in (478.1 mm) tall by 16.8 in (426.8 mm) deep envelope, with a 9.06 in (230 mm) connection pitch between phases. The drawout cradle and ArcBlok technology together mean this part is designed for switchgear lineup integration — not a standalone enclosure. Plan for the cutout and racking clearance in the gear layout before specifying.","metaTitle":"Schneider LV839306 Masterpact MTZ3 50 HB, 5000 A, 3P Drawout","metaDescription":"LV839306 Masterpact MTZ3 50 HB automatic switch disconnector, 5000 A rated, 200 kA Icu at 240 V, 3P drawout with ArcBlok.
