Metal-Oxide Varistors (MOVs) Industrial High Energy Terninal Varistors > HB34, HF34 & HG34 Series RoHS HB34, HF34 and HG34 Varistor Series Description The HB34, HF34, and HG34 Series of transient surge suppressors are industrial high-energy Metal-Oxide Varistors (MOVs). They are designed to provide surge suppression in the AC mains outdoor and service entrance environment (distribution panels) of buildings. 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 HB34 Series provides rigid terminals for through- hole solder mounting on printed circuit boards, thereby Agency Approvals eliminating the need for screw mounting. The HF34 Series has the same rigid through-hole terminals as the Agency Agency Approval Agency File Number HB34 with the addition of mounting holes for bolt-down mounting and longer terminals to allow for additional UL1449 E320116 mounting flexibility. The HG34 has formed feet with mounting holes for vertical bolt-down mounting. Additional Information See Ratings and Specifications table for part numbers.
