HB34, HF34 and HG34 Varistor Series
®
®
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.

PRODUCTS
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.

Power Dissipation Ratings
PERCENT OF PEAK VALUE
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.

O1 = Virtual Origin of Wave
T = Time From 10% to 90% of Peak
T1 = Virtual Front time = 1.25 • t
T2 = Virtual Time to Half Value (Impulse Duration)
Example: For an 8/20µs Current Waveform:
8µs = T1 = Virtual Front Time
20µs = T2 = Virtual Time to Half Value

NOTE: If pulse ratings are exceeded, a shift of VN(DC) (at specified current) of more than
±10% could result. This type of shift, which normally results in a decrease of VN(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.
