Fronius Backup Switch 1PN/3PN-63A

In the event of a power failure, the single-phase or three-phase Fronius Backup Switch enables all important loads to be supplied with power again in no time at all. This also includes all those for whom the 3 kW emergency power supply via the PV Point of the Fronius Gen24 series is not sufficient.

An all-pole backup switch disconnects or switches all conductors of a power system, i.e. the three phases (L1, L2, L3) and the neutral conductor (N), to ensure complete disconnection from the grid.

The system and the backup power consumers are disconnected from the grid and the inverter is permitted to operate independently, whereby overcurrent and overvoltage protection must be installed at suitable points to protect the backup power consumers.
