Backup Switch 1P/3P-63A

The Fronius emergency power portfolio ticks all the boxes. Our new switching components, the Fronius Backup Switch and Fronius Backup Controller, are available for cost-effective switching to full backup operation. Both are space-saving and easy to install in the distribution board. The Backup Switch is a cost-effective 3-way switch for manual switching to full backup operation, while the Backup Controller automatically switches between emergency power and mains parallel operation.
