YD11400 Lovato star delta starter 400VAC 11KW 15HP 22Amp

Why Choose the Lovato YD11400 Star-Delta Starter?

The Lovato YD11400 is a robust and reliable star-delta motor starter designed for reduced-current starting of three-phase induction motors in industrial and commercial applications. Manufactured by Lovato Electric, this enclosed starter helps minimise electrical inrush current and mechanical stress during motor startup, making it ideal for larger motor installations.

Using automatic star-delta transition technology, the YD11400 initially starts the motor in a star configuration to reduce startup current and torque before switching to delta mode for normal running conditions. This improves system stability, protects connected equipment and reduces stress on power distribution systems.

With a rated motor power of 11 kW, a 22 A AC3 operational current rating and a 400 V AC control voltage, the Lovato YD11400 is suitable for pumps, compressors, conveyors, fans and industrial machinery systems requiring dependable reduced-current motor starting.

Efficient Reduced-Current Motor Starting

Star-delta starters are commonly used for larger three-phase motors where reducing startup current is important for maintaining electrical system stability. By initially connecting the motor in star configuration, the starter lowers current draw before switching to delta operation for full-load running.

The Lovato YD11400 helps reduce voltage dips, minimise wear on motors and driven equipment, and improve operational lifespan. This makes it particularly suitable for industrial applications involving pumps, compressors, conveyors and ventilation systems.

Typical Applications

• Industrial pumps and booster systems.
• Compressors and refrigeration equipment.
• Conveyor and material handling systems.
• Ventilation and extraction equipment.
• Water treatment and agricultural systems.
• General industrial machinery and automation systems.
