Product Information
Extended Description
1SVR730885R3300 ABB: The CM-MPS.21S is a multifunctional relay from the CM three-phase monitors range. It operates with a rated control supply voltage / three-phase measuring voltage of 180-280 V AC 50/60 Hz and has a 2 c/o (SPDT) output with contacts rated at 250 V / 4 A. This relay is also suitable to monitor single-phase mains. It monitors all phase parameters such as over/undervoltage, phase unbalance, phase failure as well as an interrupted neutral. 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.

Feature → Business Impact → Application: Measuring range of 180-280 V AC with 50/60 Hz supply ensures accurate detection across typical European and international mains, reducing nuisance trips and enabling stable machine operation in panel setups. This translates to higher line uptime and lower maintenance costs for automation skids. Feature → 2 c/o SPDT contacts supports direct control logic and signaling without additional relays, cutting component count and wiring time in motor control centers and machine panels. Feature → Adjustable threshold values and selectable ON/OFF delays (0 to 0.1-30 s) allow fine-tuning to match application dynamics, minimizing false trips in processes with varying load profiles. Feature → Phase sequence monitoring, phase unbalance, and interrupted neutral detection deliver comprehensive protection for three-phase systems, helping meet stringent electrical standards in manufacturing lines. Feature → Screw terminal connections and double-chamber cage terminals offer secure, vibration-resistant wiring suitable for DIN rails and compact enclosures, expediting installation and service. Feature → IP50 housing with DIN-rail mounting supports safe, compliant installation in rugged industrial environments, while temperature range from -25 to +60 °C ensures reliable operation in factories and data centers. Certification coverage including CE, UL/CSA, and cULus, plus RoHS and REACH compliance, simplifies cross-border procurement and regulatory adherence for global OEMs and integrators.

FAQs
CM-MPS.21S mounts on DIN rails TH35-7.5 or TH35-15 and uses screw terminals with double-chamber cage construction for secure, vibration-resistant wiring. Stripping length is 8 mm, and tightening torque is 0.6-0.8 N·m, enabling quick, reliable setup in standard control cabinets.
Measuring range is (L-N) 180-280 V AC with 50/60 Hz supply. It provides 2 c/o SPDT outputs with a rated current of 4 A at 230 V AC (I_e AC-12) and 3 A (I_e AC-15). This supports direct control of small relays or signaling devices without extra relays and reduces panel wiring.
Yes. It monitors over/undervoltage, phase failure, phase unbalance, phase sequence, and interrupted neutral, making it ideal for machine control panels, power distribution, and industrial drives where reliable protection prevents unplanned downtime.
The relay is CE-marked and UL/CSA certified, with cULus and UKCA references in its documentation. It also complies with RoHS and REACH, and features IPC64-equivalent insulation ratings. This enables streamlined procurement and regulatory compliance across Europe, North America, and other markets.
The device is designed for long life with high electrical and mechanical durability. It offers a warranty with standard returns for warranty-related issues and is compatible with spare parts and accessories (e.g., sealable covers). The measurable ROI comes from reduced downtime, lower relay counts, and simplified wiring in control panels.
