Description
The Ziehl UFR1001E is a voltage and frequency monitoring relay for installations that generate their own electricity while connected to the public grid. It meets the grid-connection standards used in Germany, the UK and Austria, and trips when the grid voltage or frequency leaves the permitted range. Victron also sells it ready-built into the Anti-Islanding Box, together with contactors and a main breaker.
