The Chint SQ4-22P/IS-SD-415V is a robust enclosed star-delta motor starter with isolator designed for reliable reduced-current starting of three-phase industrial motors. As part of the trusted Chint SQ4 motor starter series, it provides dependable motor control, safe local isolation and durable protection for industrial applications.
This starter reduces motor inrush current during startup by initially operating the motor in star configuration before changing to delta operation. The integrated isolator allows safe disconnection during maintenance, while the metal clad enclosure provides protection for internal components in industrial environments.
With a 22 kW motor rating, 415 V AC control circuit, integrated isolator and IP55 metal clad enclosure, the SQ4-22P/IS-SD-415V is suitable for pumps, compressors, conveyors, fans and industrial machinery requiring dependable reduced-voltage motor starting.
Star-delta starters such as the Chint SQ4-22P/IS-SD-415V reduce motor starting current by initially connecting motor windings in a star configuration before automatically switching to delta operation. This helps reduce voltage dips, minimise mechanical stress and improve the reliability of industrial motor systems.
The integrated isolator provides secure local isolation during servicing and maintenance procedures. The SQ4 series metal clad IP55 enclosure supports dependable operation in demanding industrial environments where protection against dust and moisture is required.
