NS2 Motor Starter

SKU:NS2

The CHINT NS2 Manual Motor Starter is a compact, reliable device that provides both manual motor control and comprehensive protection against overload, short-circuit, and phase failure. Rated for operational currents up to 32 A, it combines the functions of a circuit breaker and a thermal overload relay in one unit. Built to IEC/EN 60947-2 and IEC/EN 60947-4-1 standards, the NS2 ensures safe, precise, and efficient motor starting and stopping, making it ideal for industrial machinery, pumps, compressors, and automation systems.
