Automatic recovery after 60 s when voltage returns to normal.

Built-in voltmeter for real-time voltage monitoring.

Fast DIN rail mounting in the cabinet.

Applications

For home users: protects household appliances from power disturbances.

In offices: safeguards computer systems, servers, printers.

In industry and workshops: prevents equipment failures due to voltage fluctuations.

For electricians: simplifies cabinet assembly and ensures high safety level.

Pros

Reliable electrical network protection against voltage fluctuations.

Automatic recovery ensures uninterrupted operation.

Integrated voltmeter allows constant voltage monitoring.

Suitable for both household and industrial networks.

Compact design, easy DIN rail installation.

Cons

Cannot fully protect against sudden, very short voltage spikes (for lightning strikes, additional surge protection devices are recommended).
