Why Choose the Lovato YD11400 Star-Delta Starter?
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.

Frequently Asked Questions
What is the Lovato YD11400 used for?
It provides reduced-current starting for three-phase induction motors before automatically switching to normal delta operation.
What motor size is this starter suitable for?
The YD11400 is suitable for motors rated up to 11 kW.
What control voltage does this starter use?
This model is fitted with a 400 V AC control coil.
Does the starter include an overload relay?
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.
Why use a star-delta starter?
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.
Trusted for Industrial Motor Starting
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.
