Description
The DHB34 Series of transient surge suppressors is
comprised of two industrial high-energy Metal-Oxide
Varistors (MOVs) discs placed in parallel as a single device.
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.
