1SYN372342R3800

ABB 1SYN372342R3800 (SDA-60) is a fully automatic Star-Delta motor starter designed for controlled starting of larger three-phase induction motors. ABB officially identifies this exact ordering code as the SDA-60, 220–230 V coil variant in its Star-Delta starter range. The model is specified for approximately 60 HP / 45 kW motor applications at 415 V. During starting, the motor windings are initially connected in star configuration, reducing starting current compared with Direct-On-Line starting. After the preset transition period, the starter automatically switches the motor to delta configuration for normal operation. Typical applications include large pumps, compressors, fans, blowers, conveyors, HVAC equipment, process machinery and industrial motor-control panels.
