FOXESS S-BOX

The fire safety switch FOXESS S-BOX is a device designed to control the supply of direct current from photovoltaic panels. It ensures safety by disconnecting the direct current circuit in case of a disruption in the supply of alternating current. It operates by connecting the DC circuit after the AC power is restored. This device is extremely useful in the event of a power grid failure or intentional disconnection of building power when there is a risk of fire.
