HBx/HFx/HGx Series

HB34, HF34 and HG34 Varistor Series

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.

The HB34 Series provides rigid terminals for through-

hole 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.
