YDSW30230 Lovato star delta starter with isolator 230V 30KW 40HP 60Amp

Why Choose the Lovato YDSW30230 Star-Delta Starter with Isolator?

The Lovato YDSW30230 is a heavy-duty star-delta motor starter with integrated isolator designed for reduced-current starting of large three-phase induction motors in demanding industrial and commercial applications. Manufactured by Lovato Electric, this enclosed starter combines reliable motor control with safe local isolation functionality for enhanced maintenance safety and operational reliability.

Using automatic star-delta transition technology, the YDSW30230 initially starts the motor in a star configuration to reduce startup current and torque before automatically switching to delta operation for full-load running. This controlled startup process helps minimise voltage dips, reduce mechanical stress and improve the operational lifespan of motors and connected equipment.

With a rated motor power of 30 kW, a 60 A AC3 operational current rating and a 230 V AC control voltage, the Lovato YDSW30230 is ideal for pumps, compressors, conveyors, ventilation systems and industrial process machinery requiring dependable reduced-current motor starting with integrated local isolation.

Efficient Reduced-Current Motor Starting with Isolation

Star-delta starters are commonly 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 integrated rotary isolator fitted to the Lovato YDSW30230 enables safe local disconnection during maintenance and servicing procedures. This combination of star-delta starting and isolation functionality makes the starter particularly suitable for industrial automation systems requiring both operational reliability and maintenance safety.

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.
• Heavy-duty industrial machinery and automation systems.
