Product details

The LV839066 is a Schneider Electric Masterpact MTZ3 60 HF automatic switch disconnector, rated 6000 A at 104 °F (40 °C) in a 4-pole fixed-mount configuration. The headline breaking capacity figures tell you what this part can handle with an external relay: 100 kA Icu at 254 V AC, 100 kA Icu at 508 V AC, and 85 kA Icu at 635 V AC, all per ANSI C37.50.

Fixed-mounted chassis: 39.2 in (996.3 mm) wide, 13.9 in (352.2 mm) tall, 11.7 in (297.1 mm) deep. Connection pitch is 9.06 in (230 mm). Panel builders need to account for the width — this is a full-width drawout cradle footprint, not a compact breaker. The fixed mounting mode means the switch disconnector bolts directly into the switchgear bus, no racking mechanism.
