Operating temperature: ~ -20°C to +55°C

Functions

Voltage monitoring (V) – displays real-time network voltage on the screen
Current monitoring (A) – continuously measures load current
Overvoltage protection (OV) – disconnects the circuit when voltage exceeds the set limit
Undervoltage protection (UV) – protects equipment from too low voltage
Overcurrent protection (OC) – interrupts supply when current exceeds the set limit
Surge protection – reacts to sudden voltage spikes in the network
Automatic reset – restores power when parameters return to normal
Reset time adjustment – allows setting the delay before reconnecting
Dual display – shows voltage and current simultaneously
Fault memory – allows viewing of recent faults
Adjustable protection parameters – voltage and current limits can be set as needed
Button control – easy setup via SET and arrow buttons

Application

For household users: Protects household appliances (refrigerators, boilers, inverters), suitable for home electrical panels, helps prevent damage due to voltage fluctuations
For industry / engineers: Monitoring of electrical network parameters, equipment protection in production lines, used as an additional protection layer
For electricians: Installed in panels as a compact “all-in-one” solution, quick DIN rail installation, easy configuration according to project needs

Advantages

4 protections in one device
Dual display – clear information
Automatic reset
Compact (only 1 module)
Easy installation
Suitable for both residential and industrial use

Disadvantages

Single-phase only (not suitable for three-phase systems)
Requires proper configuration of limits
May disconnect frequently in case of unstable voltage

What is this device for?

It protects household appliances from voltage spikes, overvoltage, undervoltage, and overload.

Is it suitable for home use?

Yes, it is suitable for apartments and houses – especially if you want to protect a refrigerator, boiler, TV, or other equipment.

Can it replace a circuit breaker?

No, it does not replace a circuit breaker – it is best used together, as they perform different functions.

What does the display show?

The display shows real-time voltage (V) and current (A).
