The LV839008 is a Schneider Electric Masterpact MTZ3 60 HA non-automatic switch disconnector rated at 6000 A continuous at 40 °C ambient. It's a 4-pole drawout unit built for ANSI distribution applications — think main or tie switch in large low-voltage switchgear where you need to manually isolate a bus section or a transformer feeder. Breaking capacity is 65 kA Icu at 254 V, 508 V, and 635 V AC 50/60 Hz when used with an external relay per ANSI C37.50. The short-time withstand current (Icw) is 85 kA for 0.5 s per ANSI C37.50 — a key number for selective coordination studies: downstream breakers can clear a fault while this switch holds closed through the delay. Control is push-button operated, and the drawout chassis mounting lets you rack the unit out for maintenance without unbolting bus connections — standard for switchgear where uptime and isolation safety matter.
