Functions

Overvoltage protection – automatically disconnects the network when voltage exceeds the set limit
Undervoltage protection – protects equipment from too low voltage and unstable operation
Digital display – shows network voltage parameters in real time
Automatic reset – when voltage normalizes, the relay automatically restores power
Time delay function – prevents frequent switching on/off during short-term fluctuations
High power control (up to 63A) – suitable for both household and industrial loads
Modular DIN mounting – easy integration into electrical panels
Sealed construction – ensures reliable operation and protection against environmental factors
Automatic network monitoring – continuously analyzes voltage without additional control
