Lauritz Knudsen ML2 FASD, Fully Automatic Star Delta Starter - 35 HP | Relay Range 20-32A | 360V AC | Heavy Duty

About the Product

The Three Phase Fully Automatic Star Delta Starter is a motor control & protection device designed for starting & operating three phase induction motors using reduced voltage starting.

It automatically changes from star connection to delta connection after a preset time interval, reducing starting current & minimizing mechanical stress on the motor & connected equipment. It is suitable for pumps, compressors, fans, blowers, conveyors, & industrial machinery requiring controlled motor starting.

How the Star Delta Starter Works

This starter provides efficient & controlled motor starting through an automatic transition process:

• Starts the motor in star configuration with reduced voltage

• Minimizes inrush current during startup

• Reduces mechanical stress on the motor & driven equipment

• Automatically changes to delta configuration after a preset interval

• Enables efficient motor operation at full load conditions

• Improves overall system reliability & motor performance

Star-delta starters are widely used for larger motors where direct-on-line starting may cause excessive current draw & voltage drops.
