Product Information
Extended Description
1SVR730884R1300 ABB: The CM-MPS.31S is a multifunctional relay from the CM three-phase monitors range. It operates with a rated control supply voltage / three-phase measuring voltage of 160-300 V AC 50/60 Hz and has a 2 c/o (SPDT) output with contacts rated at 250 V / 4 A. This relay monitors all phase parameters such as over/undervoltage, phase unbalance and phase failure. The corresponding threshold values are adjustable. Phase sequence monitoring as well as an ON or OFF tripping delay are selectable. 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.

Yes. CM-MPS.31S supports TH35-15 or TH35-7.5 DIN rails and uses screw terminals suitable for flexible, ferrule, or rigid conductors from 0.5 to 4 mm². Tightening torque is 0.6 to 0.8 N·m, with a wire stripping length of 8 mm. This simplifies installation and reduces panel footprint.
The relay measures (L-L) 160–300 V AC with a 50/60 Hz supply, and provides 2 c/o SPDT contacts. It offers a 200 ms startup delay and a selectable tripping delay of 0 or 0.1–30 s. Output current ratings are 4 A AC-12 (230 V) and 3 A AC-15, making it suitable for control circuits and signaling.
Yes. It monitors phase failure, phase sequence, over/undervoltage, and phase unbalance, enabling early fault detection that prevents motor damage and unplanned downtime. It is ideal for automation panels, drives, and motor feeders in manufacturing lines, conveyors, and process equipment.
CM-MPS.31S complies with CE and UL/CSA standards, including UL 508 and CAN/CSA C22.2 No.14. It also aligns with IEC/EN 63000, IEC/EN 60255-27, and IEC/EN 61000-6-2/6-3, supporting regulatory compliance for global deployments and high-assurance panels.
Lead time is approximately 28 days, with stock available in designated warehouses. The device carries standard warranty terms and a return policy for warranted units. The ROI comes from reduced downtime, improved motor protection, and faster commissioning thanks to DIN-rail mounting and straightforward wiring.
