YD22230 Lovato star delta starter 230VAC 22KW 30HP 43Amp

Why Choose the Lovato YD22230 Star-Delta Starter?

The Lovato YD22230 is a heavy-duty star-delta motor starter designed for reduced-current starting of three-phase induction motors in demanding industrial and commercial applications. Manufactured by Lovato Electric, this enclosed starter helps minimise startup current and reduce mechanical stress on motors and driven equipment, making it ideal for larger industrial motors.

The star-delta starting method initially connects the motor windings in a star configuration to lower startup current and torque before automatically switching to delta operation for normal running conditions. This controlled transition helps improve electrical system stability, reduce voltage dips and extend motor lifespan in industrial installations.

With a rated motor power of 22 kW, a 43 A AC3 operational current rating and a 230 V AC control voltage, the Lovato YD22230 is suitable for pumps, compressors, conveyors, fans and heavy-duty industrial machinery requiring reliable reduced-current motor starting.

Efficient Reduced-Current Motor Starting

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

The Lovato YD22230 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.
