Functions

Automatic voltage recovery – when voltage normalizes, the device automatically turns on.

Protection against overvoltage, undervoltage, overcurrent, leakage, and short circuit.

Leakage current detection and human protection against electric shock.

Smart pre-power-on recognition – the device checks the circuit and will not turn on if an error is detected.

Automatic shutdown when power is lost and automatic power-on when supply is restored.

Fault logging – stores disconnection reasons (date, voltage, current, leakage).

No additional grounding required – suitable for both older and modern electrical networks.

Usage

Household: Protect household appliances from power fluctuations, e.g., refrigerators, washing machines, TVs.

Commercial premises: Offices, shops, small workshops.

Industry: Communication base stations, relay equipment, video surveillance systems, data centers.

Special purpose: Protection of telemetry, measurement, alarm systems.

Advantages

Comprehensive protection in one device – against voltage, current, and leakage.

Automatic power-on – no need to physically switch the switch.

Adjustable parameters – can be customized to specific needs.

Fault memory – allows analysis of power grid problems.

Suitable for both professionals and home users.

Compact size – fits standard distribution panels.

Disadvantages

Cannot be used as the main automatic switch (requires an additional circuit breaker before it).

No isolation function – must disconnect power supply before performing work.

Parameter setting required after installation.

A smart, reliable, and universally applicable protection switch designed for everyone who values electrical safety. Due to numerous functions and quick response, it ensures a high level of protection for both people and equipment. It is an excellent choice for both professional electrical engineers and conscious home users looking for a long-term solution against unexpected power disturbances.
