Its rated insulation voltage is 690V AC, and the unit weighs 1.7kg. Dimensions are 10.6 × 7.6 × 10.4cm for DIN rail mounting.
Sub-50ms switching means the supply dip lasts less than a twentieth of a second. Lights usually ride through it, but desktop PCs may still restart.
Change Over Switch Wiring And Fit
Wire the utility grid and the inverter output to their correct source terminals. Match the switch to your main supply breaker, because a 63A unit must not carry more than 63A. Test the changeover before signing off the installation.
Swapped source wiring can damage the inverter or appliances, so check it twice. Its control circuit needs a 220V AC supply to operate. It will not suit three-phase supplies, loads above 63A or DC circuits.
Homes that prefer manual switching can use our manual 2P 63A changeover switch. Smaller solar systems can use our 5kW solar distribution board for DIN rail gear.
As a changeover switch for inverter backup, it handles single phase loads up to 63A. Pair it with a unit from our off-grid inverter range for solar backup. Our Luxpower 5kW off-grid inverter is one single phase option.
