Lovato YDSW15400 star-delta motor starter with integrated isolator rated for 15 kW three-phase motors with 28 A AC3 current rating and 400 V AC control voltage for reduced-current motor starting.
£406.67
The Lovato YDSW15400 is a premium 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 reduce motor inrush current during start-up, minimising electrical and mechanical stress while extending the service life of motors and connected equipment.
Designed for demanding industrial environments, the YDSW15400 features a durable IP65 insulated enclosure with integrated start and stop push-buttons together with a built-in rotary isolator for safe local isolation during servicing and maintenance. It is an ideal solution for OEMs, machine builders and industrial maintenance engineers requiring dependable motor control and enhanced operational safety.
With a rated motor capacity of 15 kW (20 HP), a 28 A AC-3 operating current and a 400 V AC control coil, the Lovato YDSW15400 delivers efficient reduced-voltage motor starting for pumps, compressors, conveyors, fans and a wide range of industrial machinery. A compatible thermal overload relay is selected separately to complete the installation.
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 helps reduce voltage dips, minimise mechanical shock and improve the longevity of motors and driven equipment.
The integrated rotary isolator provides a convenient means of safely disconnecting the starter during maintenance, making the Lovato YDSW15400 an excellent choice for industrial installations where reliability, safety and ease of servicing are essential.
