DESCRIBE

The ABB 1SVR730824R9300 is a three-phase monitoring relay from ABB’s CM-PFS.S series. It is designed for continuous monitoring of three-phase power supplies to detect phase failure and incorrect phase sequence. The relay measures line-to-line voltages across all three phases and activates its output contacts when an abnormal condition is detected, helping protect motors, drives, and other three-phase loads from damage. The compact design allows DIN-rail installation with screw terminal connections for easy integration into control panels.
