Product Information
Extended Description
1SVR560731R3703 ABB: The CM-UFD.M34M is a multi-functional grid feeding monitoring relay with Modbus RTU communication interface, which provides interface protection and is to be installed between a renewable energy system and the public grid. This innovative relay guarantees grid stability and seeks to prevent blackouts. If the voltage or frequency magnitudes of the public grid are outside the permited range, then the device changes status and acts to disconnect the renewable energy system from the public grid by sending a signal to a decoupling unit (e.g. contactor, switch disconnector or circuit breaker). As soon as the grid is stable again, the system may automatically reconnected. The CM-UFD.M34M provides different monitoring functions including over-/undervoltage and over-/underfrequency as well as rate of change of frequency (RoCoF) and vector shift monitoring functions, which detect a loss of mains event. This grid feed monitoring relay is certified in accordance to DEWA requirements and may be connected to the state-of-the-art cloud solution, ABB Ability Energy and Asset Manager.

The product combines multi-function voltage and frequency monitoring with ROCOF and vector shift detection to safeguard grid interfacing between renewable energy sources and the public grid. This feature-set reduces blackout risk and helps utilities maintain grid stability, which translates to higher energy availability and lower outage-related penalties in utility-scale plants. The Modbus RTU interface enables remote supervision and data integration with ABB Ability Energy and Asset Manager, supporting proactive maintenance and operational analytics for asset-intensive installations. Automatic disconnect and reconnection when grid conditions change ensures safety and compliance with grid codes while minimizing downtime for solar and wind assets. Its 0 … 540 V AC measuring range and 24 … 240 V control supply voltage simplify integration into existing control panels and control circuitry, reducing engineering time and wiring complexity. Built for DIN rail mounting (TH35), it fits standard panel designs, supports modular expansion, and streamlines retrofits in mature installations. The device’s robust durability specs—IP20 housing, 100,000 AC-12 cycles, and 30,000,000 mechanical cycles—provide long-term reliability in demanding environments and lower total cost of ownership. RoHS, CE, UKCA, and DRRG (DEWA) certifications reinforce regulatory compliance and risk mitigation for critical infrastructure projects.

FAQs
Installation is straightforward on standard TH35 DIN rails. The unit supports mounting on TH35-7.5 and TH35-15 rails, with screw terminals and a 0.5-0.6 N·m tightening torque. Ensure proper wire sizing (0.2-6.0 mm² depending on conductor type) and follow the terminal stripping length of 8 mm. This simplifies retrofits and minimizes cabinet space impact while maintaining reliable electrical connection.
The relay monitors over- and undervoltage, over- and underfrequency, RoCoF, and vector shift, along with 10-minute average value monitoring. When the public grid deviates outside permitted ranges, it commands a decoupling unit to disconnect the renewable source, and it can automatically reclose once grid conditions normalize, ensuring grid stability and compliance with DRRG standards.
Yes, the CM-UFD.M34M family provides a Modbus RTU communication interface for remote supervision. This enables integration with ABB Ability Energy and Asset Manager, SCADA, and other industrial systems, allowing operators to monitor voltage, frequency, and device status remotely, collect performance data, and trigger maintenance alerts without onsite visits.
This relay carries CE and UKCA declarations of conformity, is RoHS compliant, and aligns with DRRG DEWA requirements. It also includes TÜV reference and supports IEC/EN standards such as IEC/EN 63000, IEC/EN 60255-26, and IEC/EN 61000-6-3, ensuring regulatory compliance and reliability in utility-scale and industrial environments.
By preventing grid instability and enabling automatic disconnection/reconnection, the relay reduces downtime, protects critical energy assets, and lowers outage penalties. Its long mechanical and electrical durability, combined with remote monitoring via Modbus RTU, reduces maintenance visits and enables predictive service, improving overall asset availability and lowering total cost of ownership.
