The Achilles Heel of MOVs is that each each small hit they take become cumulative, at some point causing their failure without warning. I believe that it is Sony who developed the ZNR surge protector with which small hits do not become cumulative. They are carried by Digi-Key. To the un-initiated, you must use 3 MOVs or ZNRs for complete surge protection of a line. These must be connected as follows : one from the 'hot' wire to the neutral (white wire), one from the neutral wire to the Safety Ground wire (green wire), and the third from the 'hot' wire to the Safety Ground wire.
