ABB 1SVR730841R0300

The CM-SRS.12S serves as a single-functional current monitoring relay within the CM single-phase monitors series. It operates effectively with a rated control supply voltage ranging from 110 to 130 V AC and provides a single changeover output contact rated at 250 V and 4 A. This relay employs an RMS measuring principle to monitor both DC and AC currents across three distinct measuring ranges: 0.3-1.5 A, 1-5 A, and 3-15 A, functioning according to the open-circuit principle.

Configurable for either overcurrent or undercurrent monitoring, the hysteresis can be adjusted from 3% to 30% of the threshold value. The device is equipped with screw connection technology utilizing double-chamber cage connection terminals, ensuring reliable electrical connectivity.

Additional features include an optional sealable transparent cover to prevent unauthorized adjustments. The device's dimensions are 22.5 mm in width, 85.6 mm in height, and 103.7 mm in depth, and it weighs 0.168 kg. It is compliant with several standards, ensuring its suitability for various industrial applications.
