Important Alert: CPSC Recalls 15 million surge protectors. Click here for information.
If you are using an MOV type surge suppressor or are considering their use, please read the following:
- MOVs wear out and must be replaced every 6 months to 3 years depending on the surge environment. The “protection working light” is proof the manufacturer expects their product to fail, making their use a real gamble!
- Failed MOVs may flame, smoke, or open a fuse, removing power from critical equipment.
- Most MOV suppressor ratings are based on calculations, not actual endurance testing.
- MOVs used in “all three modes” actually endanger networked equipment, and can degrade audio, video and computer signals.
- Avoid using suppressors in plastic housings. Metal housings will impede MOV fires better.
- Do not place MOV suppressors on carpeting, near curtains or other flammable surfaces.
- Shake the suppressor periodically and listen for loose parts. Discard if it rattles.
- If the housing has burn marks (soot, discoloration), discard immediately.
