UltraMOV 25S Varistor Series
Description
The UltraMOV® 25S 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 Surge Protective Devices (SPD), Uninterruptable
Power Supplies (UPS), AC PowerTaps, 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 have 25mm square forms are produced
in a radial lead package and offered with straight leads.
UltraMOV® 25S varistors are manufactured with
Agency Approvals
recognized epoxy encapsulation and are rated for ambient
temperatures up to 85°C with no derating. This 25S Series
is LASER-branded and is supplied in bulk packaging.

For applications exceeding 85ºC ambient temperature, the
peak surge current and energy ratings must be reduced as
