How long will this surge protector last?

The owner of an I.T. panel device has the exclusive, longest and strongest warranty protection in the industry, twenty years (Protector® Products). For good reason, I.T. SPDs have been field proven to provide outstanding reliability and longevity. We expect our units to last far longer than their warranty. In fact, over the past twenty years I.T. has manufactured more than a quarter million panel devices, and the majority of products installed are still on the job today.
