Fire protection
Beny 3-string fire safety switch
Manufacturer: BENY
INDEX: BFS-S3
The BFS-S series firefighter safety switch is used to disconnect the DC-side connection of PV modules to the inverter for fire protection of roofs with solar installation, as well as for electric shock protection of people working on the roof. The switch provides complete mechanical isolation of the DC installation in case of failure. In this way, the photovoltaic installation area is safe for intervening firefighters and protects against electric shock. The switch can also be used during maintenance work carried out on the roof’s PV installation or nearby.
The BENY BFS-S3 allows the user to disconnect up to three strings of PV panels.
