HB34 Series - High Energy Industrial Varistor Series

The HB34 Series of transient surge suppressors are industrial high-energy Metal-Oxide Varistors (MOVs).

They are designed to proide surge suppression in the AC mains outdoor and service entrance environment (distribution panels) of buildings.
HB34 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.
