®
The DHB34 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. 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.
