Two answers: First the direct answer: More is better (higher is better)
Second the warning answers: There are two classes of devices we call surge protectors.. One has a digital or alpha-numeric display of some kind (the best of these give you Amps, Volts and stuff like that) the other has only a few (less than 5) indicator lights.
The alpha-numeric display may be an LCD or it may be muti-segment LED's but it too will give you either error codes (With a translation table usually stickered nearby) or error messages like "240 VOLTS"
The ones with out will not protect you from 240 volts.. Or low/high voltage, or anything other than very brief SPIKES.. Even a surge (Which can last for several seconds) which will overwhelm thise devices.
I have both on my RV.. First is the LCD type.. The LED type comes later.
