Product Information
Extended Description
1SVR560730R3402 ABB: The CM-UFD.M33 is a multi-functional grid feeding monitoring relay, 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.M33 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 complies to G99 requirements.

CM-UFD.M33 provides multi-function grid protection, including over- and undervoltage, over- and underfrequency, RoCoF, and vector shift detection. The immediate, deterministic responses reduce islanding risk and prevent grid instability, with a direct 3 c/o SPDT output to drive a decoupling unit. This enables safe shutdown and controlled reconnection, improving overall power quality and reliability for renewable installations. The relay operates over a wide measuring range (0 to 550 V AC) and supports supply from 24 to 240 V AC/DC, simplifying integration with diverse control systems and legacy panels. The screw terminals and DIN rail mounting (TH35-7.5 or TH35-15) streamline installation, while fuse-protected outputs and a minimum switching capacity of 24 V | 10 mA ensure robust, low-maintenance operation. Built for industry standards and harsh environments, it also offers IP20 protection and 3 pollution degree, reducing maintenance and enabling predictable performance in control rooms and outdoor cabinets. Durability figures—AC-12 50,000 cycles and 30,000,000 mechanical cycles—translate into lower lifecycle costs and reduced downtime, delivering a strong ROI for grid-tied projects and industrial automation deployments.

FAQs
CM-UFD.M33 is designed for DIN rail mounting on TH35-7.5 or TH35-15 rails. It uses screw terminals for flexible wiring and carries IP20 protection for controlled environments. Mounting positions 1 through 6 accommodate different panel layouts; ensure proper torque on terminals and follow fuse protection guidelines for each output circuit.
The relay monitors over- and undervoltage, over- and underfrequency, RoCoF, vector shift, and interrupted neutral. On fault detection, all three SPDT outputs drive a decoupling device to isolate the renewable source. When grid conditions normalize, the unit can automatically reconnect the system to the grid, restoring normal operation.
Yes. CM-UFD.M33 is designed for grid-tied renewable systems and complies with G99 requirements, with CE conformity and UL/CSA listings. This combination supports regulatory alignment, simplifies certification efforts, and enables safer operation for wind, solar, microgrid, and industrial applications.
Measuring range is 0–550 V AC, with rated control supply of 24–240 V AC/DC. It provides 3 c/o SPDT outputs with current ratings of up to 4 A AC-12 at 230 V and 3 A AC-15. Minimum switching capacity is 24 V at 10 mA, and outputs are fuse-protected with screw terminals for reliable field wiring.
The unit mounts on standard DIN rails (TH35-7.5 or TH35-15), aligning with ABB automation ecosystems. It fits within compact panel footprints (DIN rail-compatible width and depth) and uses screw terminals for flexible wiring. For comprehensive integration, consult CAD drawings and data sheets to coordinate with contactors, disconnectors, and compatible ABB control systems.
