Metal-Oxide Varistors (MOVs) Industrial High Energy Terninal Varistors > HB34, HF34 & HG34 Series HB34, HF34 and HG34 Varistor Series RoHS 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. Agency Approvals Agency Agency Approval Agency File Number UL1449 E320116 22.2-1 91788 The HB34 Series provides rigid terminals for throughhole solder mounting on printed circuit boards, thereby eliminating the need for screw mounting. The HF34 Series has the same rigid through-hole terminals as the HB34 with the addition of mounting holes for bolt-down mounting and longer terminals to allow for additional mounting flexibility. The HG34 has formed feet with mounting holes for vertical bolt-down mounting. See Ratings and Specifications table for part numbers.
