HB34 Varistor Series
The HB34 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. 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.
See Ratings and Specifications table for part numbers.

Power Dissipation Ratings
Should transients occur in rapid succession, the average power
dissipation result is simply the energy (watt-seconds) per pulse times the
number of pulses per second. The power so developed must be within
the specifications shown on the Device Ratings and Specifications table
for the specific device. The operating values must be derated as shown
in Figure 1.

NOTE: If pulse ratings are exceeded, a shift of V
N(DC)
(at specified current) of more than 10% could result. This type of shift, which normally results in a decrease of V ,
N(DC)
may result in the device not meeting the original published specifications, but it does not prevent the device from continuing to function, and to provide ample protection.
