ABB 1SVR730794R1300 Industrial Safety Relay Module

ABB CM-PVS 1SVR730794R1300 is a three‑phase voltage monitoring relay that belongs to ABB’s CM‑PVS family, designed to protect equipment by watching for abnormal voltage and phase conditions. It continuously monitors undervoltage, overvoltage and phase loss on a 3‑phase mains supply and provides two changeover outputs to drive control circuits or safety interlocks. The device operates on a measured input range of 3×160–300 VAC (L1–L2–L3) with an adjustable time delay from 0.1 to 30 seconds to accommodate transient fluctuations. Connections are made via screw terminals for reliable industrial wiring, and the part number 1SVR730794R1300 identifies the specific CM‑PVS variant with these voltage and output characteristics. Typical applications include motor protection, conveyors and processing equipment where robust detection of voltage faults or phase issues must trigger a controlled shutdown or safe interlock.
