It’s rare for a surge protector to experience a thermal event, but with fire-proof MOV technology, you will eliminate any worries of additional damage occurring beyond the surge protector. MOVs are the internal components that allow normal current to pass through the surge protector to your equipment, while diverting any harmful surges and spikes through the ground wire.
If the incoming voltage exceeds what the MOV can safely divert, the MOV will cut power to protect the connected equipment. In rare cases, a powerful surge could cause a conventional MOV to ignite and catch fire. Fireproof MOVs are encased in a ceramic, non-flammable material to prevent sparks or flames from occurring, protecting against electrical fires.
