Description
The UltraMOV Metal Oxide Varistor Series is designed for
applications requiring high peak surge current ratings and
high energy absorption capability. UltraMOV varistors are
primarily intended for use in AC Line Voltage applications
such as Transient Voltage Surge Suppressors (TVSS),
Uninterruptable Power Supplies (UPS), AC Power Taps,
AC Power Meters, or other products that require voltage
clamping of high transient surge currents from sources
such as lightning, inductive load switching, or capacitor
bank switching.
These devices are produced in radial lead package sizes of
7, 10, 14, and 20mm and offered in a variety of lead forms.
UltraMOVs are manufactured with recognized epoxy
encapsulation and are rated for ambient temperatures up

is supplied in bulk, ammo pack (fan-fold), or tape and reel
packaging.
