Why Choose the Lovato YDSW22400 Star Delta Starter with Isolator?
The Lovato YDSW22400 is a robust 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 reduces inrush current during motor start-up, helping to minimise electrical stress on the supply network while protecting motors and driven equipment from excessive mechanical wear.
Designed for demanding industrial environments, the YDSW22400 features a durable IP65 insulated polycarbonate enclosure complete with integrated start and stop push-buttons and a built-in rotary isolator for safe local isolation during maintenance. It is ideal for machine builders, OEMs and industrial maintenance engineers requiring dependable motor control with enhanced safety.
With a rated motor capacity of 22 kW (30 HP), a 43 A AC-3 operating current and a 400 V AC control coil, the Lovato YDSW22400 provides dependable 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 starting process reduces voltage dips, limits mechanical shock and improves the operating life of motors and connected equipment.
The integrated rotary isolator provides safe local isolation for maintenance and servicing, making the Lovato YDSW22400 an ideal choice for industrial installations where safety, reliability and long-term performance are essential.
