Lovato YD11400 star-delta motor starter rated for 11 kW three-phase motors with 22 A AC3 current rating and 400 V AC control voltage for reduced-current motor starting.
£314.86
The Lovato YD11400 is a dependable star-delta motor starter designed to reduce motor starting current while providing reliable starting and stopping of three-phase induction motors. As part of the proven Lovato L-Starter range, this enclosed starter is ideal for industrial applications where reduced inrush current is required for larger motors.
Featuring integrated Start and Stop push-button controls, the YD11400 automatically changes from star to delta operation after the preset starting period. This significantly reduces electrical stress on the supply network and mechanical stress on the driven equipment during motor start-up. The robust IP65 insulated enclosure protects the internal components from dust and water ingress, making it suitable for demanding industrial environments.
With a rated motor power of 11 kW, a 22 A operational current and a 400 V AC control coil, the YD11400 is ideally suited to compressors, pumps, conveyors and other industrial machinery requiring reduced-current motor starting. A compatible thermal overload relay is selected separately and should be set to approximately 58% of the motor full-load current for star-delta applications.
Star-delta starters reduce motor starting current by initially connecting the motor windings in a star configuration before automatically switching to delta for normal running. This proven starting method helps minimise voltage drop, reduce mechanical stress and improve the longevity of motors and driven equipment.
The Lovato YD11400 is widely used by panel builders, OEM manufacturers and industrial maintenance engineers where dependable reduced-current motor starting is required for fixed-speed industrial machinery.

It provides reduced-current starting for three-phase induction motors before automatically switching to normal delta operation.
The YD11400 is suitable for motors rated up to 11 kW.
This model is fitted with a 400 V AC control coil.
No. A compatible thermal overload relay must be selected separately and adjusted to approximately 58% of the motor full-load current for star-delta operation.
Star-delta starters reduce starting current and mechanical stress, making them ideal for larger motors where a direct-on-line start would create excessive inrush current.
Lovato L-Starter star-delta starters are trusted by OEM manufacturers, control panel builders and industrial engineers for dependable reduced-current motor starting, robust construction and reliable long-term performance.
