Low Joule rating am I protected

This question was originally posted by Charles on APC forums on 11/7/2013


I always bought APC products because of their reputation. I purchased a few surge protecters just based on the APC name. I did not realize they have different ratings. I know APC units stop working when a a surge it too powerful for the unit, so in other words I was thinking of the surge protectors as circuit breakers. I have a APC Personal SurgeArrest unit at the desk where I plug my laptop. I just found out this unit is only rates at 240 joules. Is that good enough for my laptop? What happens if a surge that is 800 joules hits my line, does the unit turn off before it can damage my computer?
