1SYN284322R3800

ABB 1SYN284322R3800 (SDA-35) is a fully automatic Star-Delta motor starter designed for controlled starting and protection of three-phase induction motors. ABB lists this exact catalogue number as the SDA-35, 220–230 V coil variant. It is suitable for approximately 35 HP / 26 kW motor applications at 415 V AC. The starter uses the Star-Delta starting method, initially connecting the motor windings in star configuration to reduce starting current. After the preset starting interval, it automatically changes over to delta configuration for normal motor operation. ABB’s SDA starter range is intended for three-phase motor ON/OFF control and protection and conforms to IS/IEC 60947-4-1. Typical applications include pumps, compressors, blowers, fans, conveyors, HVAC equipment, machine tools and general industrial motor-control systems.
