DHB34 series are industrial high-energy Metal-Oxide Varistors (MOVs), 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 eliminating the need for screw mounting.
The Littelfuse DHB34 Series consists of industrial high-energy Metal-Oxide Varistors (MOVs) designed for surge suppression in AC mains outdoor and service entrance environments, such as distribution panels. These devices are suitable for industrial heavy motors, controls, and power supplies used in oil-drilling, mining, and transportation fields, including HVAC and motor/generator applications. The series features rigid terminals for secure through-hole solder mounting on printed circuit boards, eliminating the need for screw mounting.
