Metal-Oxide Varistors (MOVs) Industrial High Energy Terminal Varistors > DHB34 Series RoHS DHB34 Varistor Series Description The DHB34 Series of transient surge suppressors is comprised of two industrial high-energy Metal-Oxide Varistors (MOVs) discs placed in parallel as a single device. They are designed to provide surge suppression in the AC mains outdoor and service entrance environment (distribution panels) of buildings. DHB34 applications also include industrial heavy motors, controls, and power supplies such as used in the oil-drilling, mining, and transportation fields, including HVAC and motor/generator applications. The DHB34 Series provides rigid terminals for through- hole solder mounting on printed circuit boards, thereby Agency Approvals eliminating the need for screw mounting.
