Joules - surge protector question
I see surge protectors with differing values for joules.... but it doesn't say what is better ... is higher better than lower values ? thanks

Lucky thing they fail open circuit. And 300 joules into a 100 joule MOV means much of the transient continues on its merry way right into your wallet. Even at 10 joules bit by bit it consumes a MOV.
Personally I have never seen a shorted MOV. TVS and GDTs yes. MOVs no.
