Product Information
Extended Description
1SVR730794R2300 ABB: The CM-PVS.81S relay is from the CM three-phase monitors range. This relay operates with a rated control supply voltage / three-phase measuring voltage of 200-400 V AC and has a 2 c/o output with contacts rated at 250 V / 4 A. The CM-PVS.81S monitors the phase parameters over/undervoltage 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.

Mount the CM-PVS.81S on TH35-15 or TH35-7.5 DIN rails and use screw terminals for wiring. Ensure supply and monitored lines are 200-400 VAC, connect the two SPDT outputs, and tighten terminals to 0.6-0.8 N·m. Use an 8 mm wire stripping length and confirm wiring is secured before power application.
Rated Operational Current AC-12 is 4 A at 230 V, AC-15 is 3 A; DC-12 is 4 A at 24 V; DC-13 is 2 A. This supports reliable control of coil and switch loads while maintaining safe isolation between input and output circuits.
Yes. It provides phase failure detection, phase sequence monitoring, and over/undervoltage monitoring, enabling timely protection against mis-sequenced or undervoltaged supply conditions that could damage motors or drive electronics.
The device is CE and UKCA certified, UL 508 listed, and CAN/CSA C22.2 No.14 compliant, with IEC/EN 63000, IEC/EN 60255-27, and IEC/EN 61000-6-2/6-3 compatibility, plus RoHS and REACH declarations for broader regulatory adherence.
Durability includes AC-12 durability of 100,000 cycles and mechanical durability of 30,000,000 cycles, reducing replacement and maintenance costs. Adjustable thresholds and delays minimize nuisance trips, lowering downtime and extending equipment life in demanding industrial environments.
