Why Choose the ABB 1SVR560730R3402 Grid Feeding Monitoring Relay?
The ABB 1SVR560730R3402, also known as CM-UFD.M33, is a multifunctional grid feeding monitoring relay designed to provide interface protection between renewable energy systems and the public grid. As part of ABB’s CM-UFD range, it monitors key voltage and frequency parameters to help maintain grid stability and support safe disconnection when abnormal supply conditions are detected.
This relay is suitable for renewable energy installations such as solar PV, wind and distributed generation systems where reliable grid monitoring is required. It provides monitoring functions including overvoltage, undervoltage, overfrequency, underfrequency, rate of change of frequency and vector shift detection.
With a measuring range of L-L 0–550 V AC and L-N 0–317 V AC, the CM-UFD.M33 is suitable for a wide range of single-phase and three-phase grid connection applications. Its 3 change-over contact outputs allow signalling to external decoupling devices such as contactors, switch-disconnectors or circuit breakers.

Reliable Interface Protection for Renewable Energy Systems
Grid feeding monitoring relays such as the ABB CM-UFD.M33 are used to monitor the quality and stability of the public grid when renewable energy systems are feeding power into it. If voltage or frequency values move outside permitted limits, the relay changes state and can signal an external disconnection device to separate the generation system from the grid.
The ABB 1SVR560730R3402 supports reliable grid protection by combining multiple monitoring functions in one compact DIN rail device. It is particularly useful in systems where accurate monitoring, fast response and dependable signalling are required for safe renewable energy connection.
Typical Applications
- Solar PV grid connection systems.
- Wind power installations.
- Renewable energy interface protection.
- Distributed generation systems.
- Grid feeding control panels.
- Industrial and commercial power monitoring applications.
