The Chint SQ4-22P-SD-240V is a robust metal clad star-delta starter designed for reliable reduced-current starting of three-phase industrial motors. Engineered for demanding industrial applications, this enclosed starter helps reduce motor inrush current during startup, minimising electrical stress and improving overall motor longevity.
Part of the dependable Chint SQ4 motor starter series, this model combines durable enclosure protection with reliable motor control functionality for industrial machinery and automation systems. The IP55-rated enclosure protects internal components from dust and moisture ingress, making the starter suitable for harsh industrial environments.
With a motor rating of 22 kW and a 240 V AC control circuit, the SQ4-22P-SD-240V is ideal for pumps, compressors, conveyors, ventilation systems and industrial process equipment requiring smooth reduced-voltage motor starting and dependable long-term operation.
Star-delta starters reduce motor starting current by initially connecting the motor windings in a star configuration before automatically switching to delta operation once the motor reaches operating speed. This helps minimise voltage dips, reduce mechanical stress and improve the reliability of industrial motor systems.
The SQ4-22P-SD-240V is designed for industrial environments requiring dependable startup performance and durable enclosure protection. Its rugged IP55 enclosure helps protect internal components against dust and moisture ingress while supporting long-term operational reliability in demanding applications.
