DESCRIBE

The ABB 1SVR703824R9300 (often listed as 1SVR730824R9300) is a three‑phase monitoring relay from ABB’s CM‑PFS.S series. It is designed to monitor the health of a three‑phase AC power supply by checking for issues such as phase sequence errors, phase failure, over‑ and under‑voltage conditions, and phase unbalance. When an abnormal condition is detected, the relay changes the state of its control outputs to signal or protect equipment. The compact relay is DIN‑rail mountable and suitable for industrial control panels and automation systems where reliable phase monitoring is required.
