Why Choose the Lovato YDSW11400 Star Delta Starter with Isolator?
The Lovato YDSW11400 is a high-quality enclosed star delta starter with integrated rotary isolator designed for the reduced-current starting of three-phase induction motors. Manufactured by Lovato Electric, this industrial motor starter combines dependable motor control with safe local isolation, helping reduce electrical inrush current, minimise mechanical stress and extend the operating life of motors and driven equipment.
Designed for demanding industrial environments, the YDSW11400 is housed in a durable IP65 insulated polycarbonate enclosure with integrated start and stop controls. The built-in rotary isolator enables safe maintenance and equipment isolation, making the starter ideal for OEMs, panel builders and maintenance engineers across a wide range of industrial applications.
With a rated motor capacity of 11 kW (15 HP), a 22 A AC-3 operational current and a 400 V AC control voltage, the Lovato YDSW11400 provides reliable reduced-voltage starting for pumps, compressors, conveyors, fans and industrial process machinery. 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 process helps reduce voltage dips, minimise mechanical shock and improve the service life of motors, gearboxes and driven equipment.
The integrated rotary isolator provides a safe method of locally disconnecting the starter during maintenance, making the YDSW11400 particularly suitable for industrial installations where both operational reliability and maintenance safety are essential.
