Dual Power Manual Transfer Disconnector, Interlock Circuit Breaker, Solar Photovoltaic System Transfer Switch
Functional features
Dual power supply switching: It can switch between two power supplies. When the common power supply fails or needs maintenance, the load can be quickly and safely switched to the backup power supply to ensure continuous power supply to electrical equipment and improve the reliability and continuity of power supply.
Isolation function: When the disconnector is in the open state, it can clearly isolate the power supply from the load, forming a visible break point, which is convenient for circuit inspection and maintenance and ensures the safety of the staff.
Product features
In the industrial field: In factories, mines and other places, many important equipment require reliable power supply. The dual power supply dual transfer disconnector can be used to ensure that the equipment can quickly switch to the backup power supply when the main power supply fails, avoiding production interruption.
In the commercial sector, such as shopping malls and hotels, to ensure uninterrupted power supply for systems like lighting, elevators, and fire protection, such disconnectors are often equipped.
Civil buildings: In some residential buildings, hospitals, data centers and other places with high requirements for power supply reliability, this disconnector can be used to ensure the power supply for key equipment.
Precautions for Use
Installation environment: It should be installed in a dry, well-ventilated environment free of corrosive gases and dust to prevent the service life and performance of the equipment from being affected by harsh conditions.
Correct wiring: Strictly follow the product manual for wiring to ensure it is secure and avoid safety hazards such as overheating and sparking caused by loose wiring.
