  GPO-3 is A fiberglass reinforced polymer laminate. This material is the industry standard for flame & arc/track resistant electrical components. GP03 also offers an excellent combination of high strength, flame resistance, and low smoke, flame, & toxicity generation. GP03 is a NEMA approved material per NEMA procedure NEMA LI-1..

  Combines high arc and track resistance, highly flame resistant. For use on 2500+ voltage equipment. 94V-O flame retardance rating. 22,100 PSI flexural strength. Red in colour

  GPO-3 Glass Polyester Laminate
GPO-3 laminate performs well in electrical applications that require high arc and carbon track resistance as well as flame resistance, physical strength, and moderate heat resistance. Grade GPO-3 laminate is used extensively in the making of phase and end barriers, insulating supports, bus bar supports and mounting panels in switchgear and other types of electrical apparatus. Grade GPO-3 is a UL recognized product with a temperature index of 120 degrees celsius electrical and 140 degrees celsius mechanical. Grade GPO-3 is produced in three standard colors: red, black, and white and is molded in thicknesses of 1/32?to 2 used for general purpose electrical and/or mechanical applications where low cost is desired. GPO-3 can withstand higher temperatures than GPO-1 or GPO-2, and has better electrical characteristics
