Frequently asked questions
Does it need to be configured before use?
Yes. Set the over-voltage and under-voltage thresholds according to the manual and the voltage requirements of your appliances before putting the protected circuit into service.
Can it protect a load larger than 63A?
No. The rated current is 63A, so the total connected load must stay below that value. For larger loads, use a device with a higher rating.
