DHB34 Series

DHB34 Varistor Series

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.
