1SYN282322R8600

ABB 1SYN282322R8600 (SDA-30) is a fully automatic Star-Delta motor starter intended for controlled starting of three-phase induction motors. ABB identifies this catalogue number as the SDA-30, 400–415 V coil version in its Star-Delta starter range. The starter is suitable for approximately 30 HP / 22 kW motor applications at 415 V AC. During starting, the motor windings are connected in star, which reduces starting current and starting torque compared with direct-on-line starting. After the preset transition period, the starter automatically changes the motor connection to delta for normal running. Typical applications include pumps, compressors, blowers, fans, conveyors, HVAC systems, machine tools and industrial process equipment where reduced starting current is preferred.
