Schneider Masterpact NW32HA 3200A 690V

The Masterpact NW32HA is a high-current switch-disconnector from Schneider Masterpact NW series, rated current 3200A, rated operational voltage 690V AC, compliant with IEC 60947-3 standard. This NW32HA supports 3-pole or 4-pole configuration, available in fixed or drawout version. HA stands for high short-circuit making capacity, Icm=143kA at 690V, with short-time withstand current Icw=65kA for 1 second, suitable for main incoming isolation and bus tie isolation in low voltage distribution systems. This unit is a switch-disconnector, not equipped with trip unit for overcurrent protection.

This NW32HA can be fitted with motor operator, auxiliary contacts, shunt release and under-voltage release for remote electrical closing and opening. It provides clear isolation position with visible contact gap, and front status indicators show on/off and fault status for on-site inspection. It supports optional communication modules for status feedback to SCADA and energy management systems. The drawout version has connected, test and isolated positions for safe maintenance without removing busbar connections.

The NW32HA is widely used in industrial substations, power plants and large commercial low voltage switchrooms for main bus isolation and backup switching. The Masterpact NW series has been superseded by Masterpact MTZ series. Many electrical service teams stock the NW32HA as spare disconnector for panel retr
