Hi Richard; all of the 30A surge protectors like the # SU39SR are for 120V service. Standard 30A RV shore power is always 120V which is why they are all designed this way. 50A surge protectors can handle 240V because it has two 120V legs.
What are you trying to use this for? If you’re trying to connect to a household 240-volt outlet or a non-standard power source, we don’t currently carry a surge protector designed for that type of setup.

Works as advertised, I assume. Haven't seen any surges yet on the device and no issues at campgrounds I've been to. Only issue is my 30amp cord doesn't quite fit under the clear plastic sleeve. Haven't seen how it performs under rainy conditions, but looks like it would not take in water and short out very easily.
