The DHB34 Series of transient surge suppressors are industrial highenergy Metal Oxide Varistors (MOVs). 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 eliminating the need for screw mounting.

See Ratings and Specifications table for part numbers.

Note:
  • Ratings are for each individual element in dual assembly.
  • Average power dissipation of transients not to exceed 2.0W per varistor element (2 varistors per device).
