Feature → Business Impact → Application: 1) Measuring ranges from 3-30 mA, 10-100 mA, to 0.1-1 A allow precise under- and overcurrent monitoring for diverse loads, reducing false trips and enabling tailored protection for motors and controllers across water, chemical, and manufacturing lines. This improves energy efficiency and lowers maintenance costs in retrofit projects. Application: motor protection in single-phase feeders and control circuits. 2) 1 c/o SPDT output rated at 250 V / 4 A provides clean, isolated signaling for interlock logic and remote alarms, enabling safer cascade protection schemes and easier integration with PLCs or safety relays. Application: PLC input signaling and safety interlocks. 3) Open-circuit measuring principle with adjustable hysteresis (3–30% of threshold) delivers stable switching, minimizing chatter in fluctuating loads and ensuring reliable alarms. Application: conveyor lines and pump stations with variable loads. 4) Screw-terminal connection, double-chamber cage terminals, and DIN-rail mounting (TH35-15/TH35-7.5) simplify installation and maintenance in crowded panels. Application: standard control cabinets and enclosure-based assemblies. 5) Robust environmental and electrical ratings (IP50 housing, 600 V insulation, 6 kV / 4 kV impulse withstand) support demanding industrial environments. Application: process and manufacturing environments with electrical noise and temperature variation. 6) Compact dimensions (22.5 mm width, 85.6 mm height, 103.7 mm depth) fit into dense DIN rail layouts, reducing panel footprint and allowing easier retrofits. Application: modernizing legacy control panels without redesigns. 7) Comprehensive standards and certifications including IEC/EN 63000, UL 508, CE, UL/CSA, and UKCA provide confidence in global deployments. Application: global machine builders and integrators needing multi-region compliance.

FAQs
The CM-SRS.11S mounts on TH35-15 or TH35-7.5 DIN rails and uses screw terminals for wiring. Flexible and rigid conductor ranges from 0.5 to 4 mm² are supported, with a recommended screw driver size of 0.8 x 4 or Pozidriv 1. Ensure correct phase and current input wiring to achieve accurate measurement across the 3 measuring ranges (3-30 mA, 10-100 mA, 0.1-1 A) and connect the SPDT output to the PLC or alarm circuit with appropriate supply isolation.
The relay provides three measuring ranges: 3-30 mA, 10-100 mA, and 0.1-1 A, using an open-circuit measuring principle. The hysteresis, adjustable from 3% to 30% of the threshold, sets the switching point stability. Configuring involves selecting the target range and adjusting the hysteresis to match the application’s permissible current fluctuations, preventing nuisance trips in variable loads.
Yes. With rated control voltage of 220-240 V AC, SPDT output for signaling, and protective features like IP50 housing and impulse withstand ratings, the CM-SRS.11S is designed for motor feeders and single-phase circuits in industrial control panels. Its robust DIN-rail mounting and shielded screw-terminal design support reliable protection for motors and pumps while complying with key standards.
The CM-SRS.11S family carries CE, UL/CSA, cULus, UKCA, CCC, and other declarations, along with UL 508 and CAN/CSA compliance. These certifications facilitate deployment across regions, ensure safety and reliability, and support traceability through CB and EAC certificates as part of a compliant electrical protection strategy.
Electrical durability is rated at AC-12 100,000 cycles, and mechanical durability at 30,000,000 operations, indicating long service life in demanding environments. The open-circuit measurement principle reduces false trips, lowering maintenance visits. Screw-terminal connections and DIN-rail mounting simplify replacement and field servicing, enabling faster ROI in steady-state operations.
