Star-Delta Starter, 30kW, 400V, Closed Transition, Timer Controlled
Star-delta starter, 30kW, 400V, closed transition, for reduced-voltage starting of medium industrial motors.
Product Overview
Star-delta motor starter, 30kW at 400V 3-phase, closed transition type. Three contactors (main, star, delta) with timer-controlled transition. Closed transition prevents current spike during star-to-delta changeover. Includes overload relay.
Closed transition — resistors maintain current continuity during star/delta changeover, preventing high transient torque. Set transition timer to achieve ~80% motor speed in star before changeover. Motor must be delta-wound and rated for voltage-to-motor connection (U, V, W and X, Y, Z accessible).
