PV fireman's switch, 2MPP, 2E/1A, 2x35A, WM4C, SPD type I+II

Rooftop Photovoltaics systems require a disconnection device at the entry of the string lines into the building, which is connected to the Power supply in the building. This allows the fire brigade to carry out extinguishing work in an emergency without being unnecessarily endangered. When the Power supply is restored, the PV Next fire brigade switch automatically switches the PV strings back on.
