YD11230 Lovato star delta starter 230VAC 11KW 15HP 22Amp

Why Choose the Lovato YD11230 Star-Delta Starter?

The Lovato YD11230 is a reliable and robust 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 is ideal for controlling larger motors while reducing mechanical stress and minimising inrush current during startup.

The star-delta starting method initially connects the motor windings in a star configuration to reduce starting current and torque before automatically switching to delta mode for normal operation. This makes the YD11230 particularly suitable for applications where direct-on-line starting may place excessive demand on the electrical supply or connected equipment.

With a rated motor power of 11 kW, a 22 A AC3 operational current rating and a 230 V AC control voltage, the Lovato YD11230 provides dependable motor starting performance for pumps, compressors, conveyors, fans and industrial machinery systems requiring controlled motor acceleration.

Efficient Reduced-Current Motor Starting

Star-delta starters are commonly used for larger three-phase motors where reducing startup current is essential. By initially connecting the motor in star configuration, the starter lowers starting current and torque before automatically switching to delta operation once the motor reaches operating speed.

The Lovato YD11230 helps reduce voltage dips, minimise mechanical wear and improve the operational lifespan of motors and driven equipment. 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.
