ABB 1SVR730840R0200 is a CM-SRS.11S current-monitoring relay with one changeover contact (1c/o) used to supervise circuit current and drive protective or signaling actions. It monitors input current over the B-C range of 3 mA to 1 A RMS and is powered from 24–240 V AC/DC. As part of ABB's CM-SRS family of measuring and monitoring relays, this model provides over- and undercurrent awareness for applications in distribution panels, motor control centers, and other electrical distribution schemes.
