ABB 1SVR730712R0200 Soft Starter

ABB 1SVR730712R0200 is the CM-MSS.32S thermistor motor protection relay with 2 changeover contacts (2c/o) and a 24 VAC/DC coil, designed to monitor a single thermistor input for motor winding temperature protection. It provides short-circuit detection and dynamic interrupted wire detection, with auto, manual, or remote reset, and is ATEX approved. The unit uses screw-terminal connections in a double-chamber cage terminal style and supports one sensor circuit to trigger its changeover outputs when the temperature threshold is exceeded. Typical applications include motor protection for AC motors in industrial equipment such as fans and pumps, where a PTC thermistor is used to monitor winding temperature.
