ABB 1SVR730700R0200 Industrial Safety Relay Module

ABB CM-MSS.22S 1SVR730700R0200 is a thermistor-based motor protection relay that monitors motor winding temperature via a single external PTC sensor integrated in the motor circuit. It is powered from 24 V AC/DC and uses two Form-C (DPDT) contacts for switching, with screw-terminal connections for reliable field wiring. The unit supports automatic, manual, or remote reset, allowing flexible protection and reset workflows in industrial motor control setups. This model, part of ABB's CM-MSS.22S family, is designed for applications requiring temperature-based protection of electric motors and reliable signaling through its DPDT outputs.
