DESCRIBE

The ABB 1SVR430824R9300 is a three-phase monitoring relay (CM‑PFS series) designed to monitor three-phase supply for correct phase sequence, phase presence, and voltage within specified limits. If a phase failure, phase reversal, or voltage anomaly is detected, the relay actuates and opens its output contacts, protecting motors and equipment from incorrect supply conditions. The relay is compact, DIN-rail mountable, and suitable for installation in control panels, motor control centers, and switchgear. It is powered directly by the measured three-phase supply.
