PT80 PT40

Local Panel Protection

Small, yet packed with the latest technology available for transient voltage surge suppressors. The PT80 and PT40 contain high peak current fuses and large thermally protected varistors that provide both reliable and safe protection for electronics. The units are ideal for use on local service panels, generators, transfer switches, dedicated equipment, OEM equipment and residential applications. Many useful standard features are designed in, including a set of relay contacts for remote monitoring, LED status indicators, and a rugged NEMA type 1 powder coated steel enclosure. The protectors are backed by our "No Nonsense" 20-year warranty and are UL1449, 2nd Ed. Listed, including the new requirements of February 9th, 2007.
