ABB ST201M-K20 Soft Starter Module For Three-Phase Motors

ABB ST201M-K20 Soft Starter Module For Three-Phase Motors provides controlled voltage ramping to start three-phase motors, reducing inrush current and mechanical stress during startup. It is rated for 20 A at 480Y/277 V and offers a 10 kAIC short‑circuit current rating, with a K‑Curve starting profile tuned for smooth acceleration of typical loads. The unit is UL 1077‑listed, signaling recognized protection suitable for inclusion in control panels and locally mounted starter assemblies. Typical applications include small to medium industrial motors in conveyors, pumps, fans, and machine tools, where ABB soft‑starter technology can provide gentle acceleration without sacrificing performance.
