I cannot find any specifications on that SPD, which is concerning because I have no idea what the level of protection that device provides.
The Eaton SP1-240S provides 50,000 Amps of surge protection per phase, many big box stores ones are only 10,000 Amps. The Eaton SP1-240S has a 20,000 Amp discharge current rating, and has a short circuit current rating of 200,000 Amps.
With surge protection devices it is very important to compare apples to apples! There are a lot on the market that are complete junk.
