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

MOV's get "used up" when they get heat stressed. They get heat stressed because there's not enough of them. If you got a MOV rated at 100 joules and along comes a 300 joules transient, guess what, the part will get heat stressed.
Again, it all boils down to more is better.
