Low Voltage Insulators

nVent ERIFLEX offers a full range of low-voltage stand-off with a total of 29 sizes available. The cost-effective insulators offer great stability of electrical and mechanical parameters and very high resistance to leakage current. The insulators are manufactured from a halogen-free fiberglass-reinforced thermalset unsaturated polyester molded compound (BMC). Their electro-plated zinc inserts are threaded to ASME® standards. The insulators work in temperatures from -40°F to 266°F. The stand-off insulators meet the requirements of UL® 94 VO for self-extinguishing materials and are UL Recognized to Standard 891, Annex G, Dead-front Switchboards and Accessories, File No.E125470. The insulators are also UL recognized for Canada for material and strength. nVent ERIFLEX insulators are the first on the market to be in compliance with the CSA® standard.
