Technical Specifications:

Number of poles: 4 poles (4P)
Current rating: 63A
Installation: DIN rail mounting for easy installation in electrical panels
Operating principle: Automatically switches power sources from primary to backup (and vice versa) during power supply disruptions
Voltage: Suitable for alternating current systems
Type of operation: Uninterruptible power switch (ensures minimal supply interruption)
Operating temperature: Designed to operate in standard indoor conditions without violating normal working temperatures (typically from -25°C to +55°C)
Usage:

Industrial and commercial premises: This switch is an ideal solution for industrial and commercial areas where maintaining an uninterrupted power supply is crucial, even when the primary supply is interrupted. It automatically switches the power supply to the backup source, protecting essential equipment from electrical disturbances.
Households: Can be used in larger households where generators or other backup power sources are installed. Ensures that in the event of power supply interruptions, the home system can switch to the backup power source without manual intervention.
Electrical distribution systems: Used in electrical distribution cabinets where selection between two power sources (e.g., grid and generator) is required.
Pros:

Uninterrupted switching: Ensures smooth and almost instantaneous switching with minimal impact on power supply.
Automatic protection: The device automatically switches to the backup source if the primary supply is interrupted, thus protecting appliances from electrical disturbances.
Easy installation: DIN rail mounting allows for quick and simple installation of the switch in the electrical panel.
Versatile application: Can be used in industry, commerce, and households where stable power supply is necessary.
Compact design: The device does not take up much space in the panel and integrates well with other equipment.
Cons:

For AC systems only: The device is intended only for alternating current (AC) systems and is not suitable for use in DC networks.
Limited current capacity: For higher current demands than 63A, a higher capacity switch may be required.
Dependence on voltage stability: In some cases, with minor electrical disturbances, additional protective devices may be needed to prevent frequent switching cycles.
The dual-power automatic switch is a reliable and practical solution for ensuring uninterrupted power supply, especially in places where the primary electricity supply may be unstable. This device is an excellent choice for industrial, commercial premises, and even homes where a stable and reliable power supply is required.
