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 through­hole 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.
