What is Difference Between 30 amp Surge Protectors from Hughes Autoformers


I see a couple of different 30amp surge protectors. One about $ and the other about $2. What’s the difference? I know nothing about surge protectors. I have a 2021 Airstream which requires 30Amp. I also do not want a surge protector that boosts voltage as I understand those can be a problem? Thanks!


Helpful Expert Reply:

Between the two 30 amp surge protectors you are looking at the # HU97FR and the # HU67FR the difference is tha the # HU67FR has an emergency shut off for the power to the RV that will stop any power from getting to the RV if the power falls above or below a specific range whereas the # HU97FR just works to prevent surges from making their way to the RV but does not totally shut off power if there's something out of range.
