Why Choose the Lovato YDSW22230 Star Delta Starter with Isolator?
The Lovato YDSW22230 is a heavy-duty enclosed star delta starter with integrated rotary isolator designed to provide reliable reduced-voltage starting for three-phase induction motors. Manufactured by Lovato Electric, this industrial motor starter helps minimise motor inrush current during start-up, reducing electrical stress on the power supply while protecting motors and driven equipment from excessive mechanical wear.
Designed for demanding industrial environments, the YDSW22230 is housed in a durable IP65 insulated polycarbonate enclosure with integrated start and stop push-buttons and a built-in rotary isolator. The isolator provides a convenient means of safely disconnecting equipment during servicing and maintenance, making this starter ideal for OEMs, panel builders and industrial maintenance engineers.
With a rated motor capacity of 22 kW (30 HP), a 43 A AC-3 operating current and a 230 V AC control coil, the Lovato YDSW22230 is suitable for pumps, compressors, conveyors, ventilation systems and other industrial machinery requiring dependable reduced-voltage motor starting. A compatible RF38 thermal overload relay is selected separately to complete the installation.

Reliable Reduced Voltage Motor Starting
Star delta starters reduce the current drawn during motor start-up by initially connecting the motor windings in a star configuration before automatically switching to delta operation. This controlled starting method reduces voltage dips, limits mechanical shock and improves the operating life of motors, gearboxes and driven equipment.
The integrated rotary isolator enables safe local isolation during maintenance, making the Lovato YDSW22230 an excellent solution for industrial applications where safety, reliability and ease of servicing are essential.
