The Chint SQ4-11P-SD-240V is a high-performance metal clad star-delta starter engineered for reduced-current motor starting in industrial applications. Designed for reliable operation and extended motor protection, this enclosed starter helps minimise inrush current during motor startup, reducing electrical stress on motors and power systems.
Part of the dependable Chint SQ4 motor starter series, this unit combines robust industrial construction with simplified motor control functionality for three-phase motors. Its durable metal enclosure and IP55 protection rating make it suitable for factories, workshops and demanding automation environments where operational reliability is critical.
With a motor rating of 11 kW and a 240 V AC control circuit, the SQ4-11P-SD-240V is ideal for pumps, compressors, fans, conveyors and machinery requiring reduced-voltage starting performance and dependable long-term operation.
Star-delta starters are designed to reduce motor starting current by initially connecting the motor in a star configuration before switching to delta operation during normal running. This helps reduce voltage dips, mechanical stress and wear on motors during startup.
The Chint SQ4-11P-SD-240V provides dependable reduced-voltage motor control for industrial environments where large motors require smoother starting performance. Its enclosed IP55 construction helps protect internal components against dust and moisture ingress in demanding applications.
