ABB 1SVR730841R0500 is a CM-SRS current-monitoring relay designed for single‑phase AC mains. It is powered from 110–130 V AC and provides two changeover contacts (2C/O) for independent signaling of current conditions. The device monitors current in the 0.3–15 A RMS range, enabling integration with safety controllers or PLCs to detect out‑of‑range loads and drive protection circuits.
