I’m not an engineer, so I’m not qualified to discuss the science. But I studied quite a bit about these after a lightning strike took out 3 TVs, a computer, a router, and a modem. There is a big difference in performance between cheap surge protectors and this product. You can spend a lot more as well, but this seemed to have solid specs in a reasonable price range. Of course, the only proof of performance would be a failure, so it’s finally an act of faith. I bought three of them.
Sorry, there was a problem. Please try again later.The most important specs for any electronic equipment surge protection are 1) Clamping voltage. 330 V. is good. 400 V. is okay. 500 V. is something, but not much. If no clamping voltage is specifically listed on the device, don't buy it. 2) Peak let-through voltage would be the ultimate spec; but I don't think this is in any organization's current standard. I know I can't find any products with that characteristic listed. BTW, ALL surge protectors degrade over time. Each time there is power outage or a voltage spike, a little bit of the protection is eaten away. After five years or so, almost any suppressor that actually works probably needs to be replaced. Of course, if you buy one that DOESN'T work (the ones that don't LIST a clamping voltage), then it doesn't matter....
