Product Information
Extended Description
1SVR730840R0200 ABB: The CM-SRS.11S is a single-functional current monitoring relay from the CM single-phase monitors range. This monitoring relay operates with a rated control supply voltage of 24 - 240 V AC / DC and has a 1 c/o (SPDT) output contact rated at 250 V / 4 A. It provides a RMS measuring principle for DC and AC currents with 3 measuring ranges: 3-30 mA, 10-100 mA and 0.1-1 A and works according to the open-circuit principle. The CM-SRS.11S is configurable for over- or undercurrent monitoring, the hysteresis is adjustable within a range of 3 to 30 % of the threshold value. A sealable transparent cover for protection against unauthorized changes is available as accessory. The device offers screw connection technology with double-chamber cage connection terminals.

FAQs
Install the CM-SRS.11S on a standard TH35 DIN rail. Connect supply and load to the screw terminals, ensuring the wiring matches the three measuring ranges. Tighten terminals to 0.6–0.8 N·m, and use the SPDT output for signaling. Verify 24–240 V supply compatibility and secure the cover if available to prevent tampering.
The relay provides three measuring ranges: 3–30 mA, 10–100 mA, and 0.1–1 A. Select the range closest to your monitored current to optimize sensitivity and hysteresis settings. The device uses RMS measurement for both AC and DC currents and offers adjustable hysteresis from 3% to 30% of the threshold.
Yes. CM-SRS.11S carries CE and UKCA declarations and UL/CSA ratings, with compatibility for IEC standards and UL 508. This ensures compliance for industrial control panels and safety-critical applications in North American and international environments.
Yes. The device operates from a 24–240 V AC/DC supply and uses RMS measuring for both AC and DC currents, making it suitable for mixed-supply systems and modern automation panels.
