Choose countryThis digital voltage and current monitoring relay is designed to protect single-phase electrical equipment from overvoltage, undervoltage, and overcurrent conditions. It is engineered for 230V AC single-phase circuits with a rated current of up to 63A.
Operating Principles and Key Functions
The microprocessor-based device continuously measures line voltage and current, displaying real-time values on a digital readout. When parameters fall outside configured limits, the relay disconnects the circuit and automatically re-engages power once voltage stabilizes.
- Overvoltage and undervoltage protection
- Overcurrent protection with adjustable limits
- Automatic reconnection with programmable recovery delay
- Real-time digital voltage and current metering
Installation and Application
Featuring a compact enclosure, the device mounts conveniently on a standard 35 mm DIN rail. Terminals accept both copper and aluminum wiring. It is suitable for residential, commercial, and industrial distribution boards. Note: This relay handles continuous power grid fluctuations and is not intended to replace surge protective devices (SPD) designed for lightning impulses.

How is the protection relay mounted?
The device is designed for snap-on mounting on standard 35 mm DIN rails inside distribution panels.
Which conductors are compatible with the connection terminals?
Both copper and aluminum wires can be used for electrical connections.
Does this relay protect against lightning surges?
No, it protects against network voltage and current fluctuations. Dedicated surge protective devices (SPD) are required for lightning impulses.
