The ABB CM-SRS.M (SVRR) is a multifunctional current monitoring relay designed for single-phase AC or DC applications. It offers three selectable measuring ranges—– mA, – mA, and .– 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 (.– s) and hysteresis (–%) enhance its adaptability to various applications. The device features a compact . mm housing with screw terminals and LED indicators for operational status.
