Functions

Overvoltage protection – automatically disconnects the power network when voltage rises to dangerous levels and protects electrical equipment from damage.
Undervoltage protection – protects equipment from unstable operation or overheating when the network voltage becomes too low.
Current limiting function – monitors load current and protects against overloads or short-circuit consequences.
3-phase network monitoring – continuously analyzes phase conditions and helps protect three-phase equipment.
Synchronous / asynchronous operation monitoring – allows detection of incorrect network operation or phase mismatches.
Digital LED display – shows real-time network parameters and protection status.
Adjustable protection settings – allows configuration of voltage limits, current limits, and delay times.
Automatic reset – once the network stabilizes, the relay can automatically restore power supply.
DIN rail mounting – convenient integration into electrical distribution boards and automation cabinets.
Equipment protection against failures – helps reduce the risk of damage to motors, pumps, inverters, and electronics.
