Product Information
Extended Description
1SVR730841R0500 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 110 - 130 V AC 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 1SVR730841R0500 current monitoring relay operates from a 110-130 V AC control supply, enabling straightforward integration with common control circuits and minimizing the need for additional power infrastructure. Business impact: faster setup and lower wiring complexity in control panels, improving project timelines and reducing commissioning costs. Application: ideal for single-phase motor protection and circuit monitoring where space and maintenance constraints demand compact, reliable relays that mount on DIN rails. The device provides three measuring ranges (0.3-1.5 A, 1-5 A, 3-15 A), delivering precise protection across varied load profiles; this translates to consistent protection without over-tripping and reduced equipment wear. Application: motor starters, feeders, and sensing circuits in manufacturing lines where current thresholds must adapt to changing loads while maintaining safety. With 2 c/o SPDT outputs, wiring flexibility increases, supporting alarms, interlocks, and stop signals without additional relays. This flexibility lowers total cost of ownership by reducing part counts and simplifying maintenance.The CM-SRS.22S uses an open-circuit measuring principle and offers an adjustable hysteresis of 3 to 30% of the threshold and a trip delay from instantaneous to 0.1–30 s. Business impact: better discrimination between transient faults and persistent faults, resulting in fewer trips and improved process continuity. Application: critical power distribution and machine protection where fast yet selective tripping is required. Screw-terminal connectivity and reliable DIN-rail mounting simplify installation and support easy replacement during maintenance windows. The device conforms to stringent standards (IEC/EN 61000-6-2, 61000-6-3, UL 508) and provides robust electrical durability (AC-12 100000 cycles) for long service life, making it a solid fit for high-demand plants. Business value: predictable performance, easier regulatory compliance, and longer equipment life across industrial facilities.

FAQs
The 1SVR730841R0500 is designed for DIN rail mounting on TH35-15 or TH35-7.5 rails, aligning with standard ABB CM-SxS installations. It uses screw terminals for secure wiring and supports straightforward replacement in existing panels. This simplifies retrofits and new builds alike, reducing installation time and ensuring consistent electrical clearances in compact control cabinets.
The relay provides measuring ranges of 0.3-1.5 A, 1-5 A, and 3-15 A, enabling accurate protection across a variety of motor sizes and loads. By selecting the appropriate range, you minimize nuisance trips while preserving fast response to genuine faults, improving overall machine uptime and safeguarding expensive drives and motors.
Yes. The CM-SRS.22S supports over- and undercurrent monitoring with an adjustable hysteresis (3–30%) and a configurable tripping delay (0 s to 0.1–30 s). This combination provides selective protection, reduces false trips on transient events, and ensures prompt shutdown during genuine faults, maintaining process safety and equipment integrity.
The device carries CE and UL/CSA approvals, with UKCA declarations and compliance to IEC/EN standards relevant to monitoring relays. It also features IP50 housing and IEC/EN 61000-6 series compliance for immunity and emission, supporting safe operation in industrial panels and adherence to international regulatory requirements.
With adjustable trip delays and hysteresis, robust open-circuit current sensing, and durable screw-terminal connections, the relay reduces nuisance trips and simplifies diagnostics. Its DIN-rail compatibility and CM-SxS family interoperability streamline spares management, shorten maintenance windows, and lower total cost of ownership through fewer replacements and easier commissioning.
