Star Delta Starters

Star delta starters are used to start large three-phase motors efficiently by reducing the initial inrush current and mechanical stress on start-up. The motor begins in a star (Y) configuration to limit voltage, then automatically switches to a delta configuration for full power operation. Ideal for high-power applications such as pumps, compressors, and industrial machinery, star delta starters help extend motor life and improve energy efficiency. Available with overload protection and timer control, they ensure safe, reliable performance. Explore dependable star delta starter solutions—available now at CEF.
