Technical Description:

Number of Poles: 4 poles (4P)
Rated Current: 100A
Switching Modes: Automatic and manual
Function: Automatic power source switching between two input sources
Voltage Range: Depends on the power supply voltage system (most commonly used with 220/380V systems)
Operating Temperature: -25°C to +70°C
Mounting: On DIN rail
Protection Measures: Integrated short-circuit and overload protection

Usage:

This dual power automatic/manual switching switch is designed to automatically switch between the main and backup power source. When the main power source fails or becomes insufficient, the device automatically switches the system to the backup source. This switch is used in various fields where ensuring uninterrupted power supply is essential, such as:

Industrial and commercial facilities
Hospitals
Data centers
Schools
Administrative buildings
The switch can operate in both automatic and manual modes, allowing the user to choose the switching time or let the device do it automatically.

Pros:

Automatic switching function: Ensures continuous power supply to critical systems by quickly switching to the backup source when the main power is interrupted.
Manual control option: Allows the user to manually switch the power source, which can be useful during maintenance or testing.
High current: 100A capacity allows the device to be used in high-load systems, suitable for industrial and commercial applications.
Overload and short-circuit protection: Ensures safe power supply, protecting systems from potential damage and ensuring longevity.
Universal mounting: Can be mounted on DIN rails or with screws, providing flexibility in installation in various locations.
Cons:

Higher cost: Due to the automatic functions and high power rating, this switch may be more expensive than simple single power switches.
More complex installation: Requires some knowledge and qualification in electrical installation, so installation may need the help of a specialist.
Dependence on backup power: If the backup source is improperly prepared or fails, the device will not be able to function as intended.
Energy consumption: Certain automation functions may consume a small amount of energy even in standby mode, which may be unnecessary for smaller systems.
Limited environmental condition range: Suitable only for certain environments, as IP20 protection class may be insufficient for outdoor conditions without additional protection.
