Voltage Protection Device — Photovoltaic Automatic Reclosing System 
Application
Photovoltaic automatic reclosing system has automatic closing in a certain case and automatic interruption in case of power failure.
At the same time, it has the functions of fault prevention, closing, overload and short circuit protection.
It is suitable for AC 50Hz, rated working point AC2320V (1P+N, 2P), AC400V (3P+N, 4P), and rated current 6A-125A circuit to automatically divide and close the circuit.
This product is widely used in the grid connected system between the photovoltaic and the city and the city.
When the electric power supply circuit breaker is automatically reconnected to realize the parallel use of the city electricity and the photovoltaic power generation, the circuit breaker automatically disconnects to block the parallel connection between the city electricity and the photovoltaic power after the power failure of the city, and the maintenance personnel can not be used in the situation that the personnel are difficult to close. Coordination in place.
It can also be used as an infrequent switch for the line.
