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. Rate 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.
