The commercial grade protectors are quite a bit more sophisticated than the few small MOV's network in the small residential units. A look inside a Joslyn is instructive about what it probably *really* takes to protect against serious surges. They have means to maintain protection since MOVs degrade with hits .

If you really have a recurring serious surge problem then spending several hundred bucks may be worthwhile see

There are cheaper/less capable models as well.
