Product Information
Extended Description
1SVR730841R1300 ABB: The CM-SRS.12S 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 220 - 240 V AC 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: 0.3-1.5 A, 1-5 A and 3-15 A and works according to the open-circuit principle. The CM-SRS.12S 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.12S on TH35 DIN rails (TH35-15 or TH35-7.5) with a 22.5 mm width. Use the screw terminals for flexible or rigid conductors (0.5–4 mm²). Tighten to 0.6–0.8 N·m and strip 8 mm of insulation. Ensure the supply is 220–240 V AC and that the output SPDT contacts are wired to the process signal or interlock circuit. The device supports secure, vibration‑tolerant mounting for industrial environments.
CM-SRS.12S monitors three RMS current ranges: 0.3–1.5 A, 1–5 A, and 3–15 A. The RMS measuring principle provides accurate readings for both AC and DC components, enabling reliable over‑ or undercurrent monitoring across common loads. This reduces misdiagnosis of transient spikes and ensures protection settings reflect actual operating conditions.
Yes, CM-SRS.12S is designed for motor protection within automation panels. It offers a single functional 1‑c/o SPDT output rated at 250 V / 4 A, which can drive interlocks, alarms, or PLC inputs. With its configurable hysteresis, you can tailor protection to motor inrush and startup behavior, balancing protection and downtime.
The CM-SRS.12S carries CE and UL/CSA (cULus) listings, UKCA, CCC, and CB certificates, along with IEC/EN 61000‑6‑2/3 and UL 508 among others. These certifications support regulatory compliance, safety in industrial environments, and suitability for global deployments across automation projects.
CM-SRS.12S is built for durability, with AC‑12 electrical durability rated at up to 100,000 cycles and mechanical durability around 30,000,000 operations. The sealable cover option helps prevent tampering, while screw terminals and DIN rail mounting simplify field wiring and routine inspections, reducing maintenance time and extending service life in challenging environments.
