ABB - 1SVR430840R0600 CM-SRS.M1 - Current Monitoring Relay, 3–30 mA to 1 A

The ABB CM-SRS.M1 (1SVR430840R0600) is a multifunctional current monitoring relay designed for single-phase AC or DC applications. It offers three selectable measuring ranges—3–30 mA, 10–100 mA, and 0.1–1 A—allowing precise monitoring of overcurrent or undercurrent conditions. Equipped with two changeover (SPDT) contacts, the relay provides reliable switching capabilities. Adjustable start-up and tripping delays (0.1–30 s) and hysteresis (3–30%) enhance its adaptability to various applications. The device features a compact 22.5 mm housing with screw terminals and LED indicators for operational status.
