It is a 4-pole drawout unit rated 4000 A continuous at 40 °C, built for distribution-level switching and isolation in ANSI-based power systems. The 65 kA Icu breaking capacity at 254 V, 508 V, and 635 V AC 50/60 Hz (with external relay per ANSI C37.50) means it can safely interrupt fault currents up to that level across the common low-voltage distribution voltages — the same rating at three voltage points, not a derated curve. The short-time withstand current is 85 kA for 0.5 s per ANSI C37.50, which governs coordination with downstream breakers during a fault-ride-through event. Drawout mounting on a chassis support — the unit withdraws from its cradle for safe isolation during maintenance without unbolting power cables. The 4-pole configuration covers three-phase plus neutral switching, standard for distribution switchboards. Physical footprint: 40.5 in wide by 18.8 in high by 16.8 in deep. Connection pitch is 9.06 in, which sets the bus-bar spacing in the switchgear lineup. Control is via push-button on the front fascia.","metaTitle":"LV839000 Masterpact MTZ3 40 HA Switch Disconnector, 4000 A","metaDescription":"LV839000 Masterpact MTZ3 40 HA non-automatic switch disconnector, 4000 A rated current, 65 kA breaking capacity, 4-pole drawout.
