Hi all

I am looking for a help in what could be a root cause analysis of repeated false operations of Solid State LV Breakers Digitrips. The digitrips were tested and found OK. However it creates false operation from time to time. Does the aging be a reason of the same? Those devices are about 13 years old in operation.

Thanks
