Varistor Protection Arresters Feature Enhancements

New Enhanced Varistor Protection (EVP) arresters are now available superseding the Ohio Brass (OB) PVN family of arresters. Built on 20 years of Ohio Brass by Hubbell Power Systems experience, EVP arresters have a robust sealing system.

A slotted tripod base gives flexible installation fitting 8 ¾” and 10” bolt circles. Grading ring usage is optimized. Sustainable features and intelligent catalog numbering system, too. EVP arresters offer the same housing material, mechanical strength, protective level and energy rating as the Ohio Brass PVN arrester family.
