Product Information
Extended Description
1SVR730840R0500 ABB: The CM-SRS.22S 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 2 c/o (SPDT) output with contacts 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.22S is configurable for over- or undercurrent monitoring. The hysteresis is adjustable within a range of 3 to 30 % of the threshold value and the tripping delay is adjustable over a range of instantaneous to 30 s (0, 0.1-30 s). 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.

The CM-SRS.22S employs RMS current measurement across three ranges (0.3-1.5 A, 1-5 A, 3-15 A), enabling precise sensing without the need for additional shunts. This translates to accurate protection thresholds and reduced nuisance trips, which minimizes downtime in critical lines such as conveyors and pumps. The 2 c/o SPDT outputs provide flexible signaling and control, allowing one contact to drive a warning circuit while the other controls a safe-stop interlock, simplifying PLC integration and wiring complexity. A wide control-supply voltage of 24-240 V AC/DC supports diverse control panels and remote installations, reducing spare parts inventory. Adjustable hysteresis (3-30%) and a trip delay (0-30 s) enable stable protection during voltage transients and startup surges, improving overall equipment reliability. The device is designed for DIN-rail mounting (TH35-15 or TH35-7.5) with screw terminals, promoting fast installation and secure connections in crowded enclosures. IP50 housing protects the electronics from dust and contaminants, while terminal IP20 ratings maintain safe operation under typical panel conditions. Certifications such as CE and UL/CSA reinforce compliance with global safety standards, facilitating cross-border deployments. In practice, these features support compliant motor protection, feeder monitoring, and panel-level safety interlocks, delivering measurable gains in uptime and maintenance efficiency.

FAQs
The CM-SRS.22S is designed for DIN-rail mounting on TH35-15 or TH35-7.5 rails and uses screw terminals, accommodating flexible (1x 0.5-2.5 mm²) or rigid (1x 0.5-4 mm²) conductors. This configuration simplifies panel wiring, improves vibration resilience, and enables secure, serviceable connections in compact control enclosures.
Measuring ranges are 0.3-1.5 A, 1-5 A, and 3-15 A with RMS current sensing for both AC and DC. The hysteresis is adjustable from 3% to 30% of the threshold, and the trip delay is selectable from instantaneous to 0.1-30 seconds, allowing tailored response to startup transients and voltage fluctuations.
Yes. The CM-SRS.22S is well-suited for single-phase motor protection and control-panel monitoring. It provides two SPDT outputs for status signaling and interlock control, supports a wide input voltage, and offers precise threshold configuration to guard motors, fans, and pumps against overcurrent and undercurrent events while minimizing nuisance trips.
The CM-SRS.22S carries CE and UL/CSA approvals and complies with multiple standards relevant to industrial electronics, including RoHS and UL 508. The housing is IP50 (terminals IP20), suitable for harsh environments inside electrical cabinets, with additional safety and conformity declarations to support global deployment.
The relay’s robust construction, wide operating range, and long electrical/mechanical durability support low maintenance needs and extended service life. With reliable protection reducing downtime and fewer mis-trips, the device contributes to a faster return on investment through improved uptime, simplified wiring, and consistent protection across multiple machines in a production line.
