1SYN244322R8600

ABB 1SYN244322R8600 (SDA-20) is a fully automatic Star-Delta motor starter designed for controlled starting of three-phase induction motors. ABB identifies this exact ordering code as the SDA-20 with a 400–415 V AC coil in its Star-Delta starter range. The starter is rated for approximately 20 HP / 15 kW motor applications, with an operating voltage of 400 V AC. During starting, the motor is initially connected in star configuration to reduce starting current; the starter then automatically transitions to delta connection for normal running. It is suitable for applications such as pumps, compressors, fans, blowers, conveyors, HVAC systems, machine tools and industrial process equipment where reduced starting current is desirable.
