The LV839095 is a Schneider Electric Masterpact MTZ3 60 HC automatic switch disconnector rated 6000 A at 104 °F (40 °C) — that's the continuous current it carries without derating in a typical 40 °C enclosure environment. The 200 kA Icu at 508 V AC (with external relay per ANSI C37.50) tells you the interrupting capacity available for fault clearing at that voltage; the same unit also carries 130 kA Icu at 635 V AC. For a 6000 A frame, those are high-end SCCR figures that give selectivity headroom downstream. This is a 3-pole drawout unit on a chassis mount, meaning the moving portion withdraws from the cassette for safe isolation and maintenance without unbolting power cables. The push-button control type covers the standard open/close/trip interface on the front escutcheon.
Physical footprint: 31.07 in (789.1 mm) wide, 18.8 in (478.1 mm) tall, 16.8 in (426.8 mm) deep. The 9.06 in (230 mm) connection pitch matches standard bus-bar or cable-riser spacing in ANSI switchgear lineups. This is a drawout breaker — the cassette frame stays bolted to the chassis; the breaker element slides in and out on rails, so panel builders need to account for the full depth plus clearance for the racking mechanism. Single unit per package. The device short name MTZ3 60 HC identifies the frame size (MTZ3) and the high-capacity rating tier (60 HC).
For a 6000 A drawout breaker at this interrupting capacity, lead time is typically project-quoted rather than off-the-shelf; submit an RFQ for the specific quantity and ship-to location.
