UltraMOVTM 25S Varistor Series
RoHS
Description
The UltraMOVTM 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.
UltraMOVs are manufactured with recognized epoxy
encapsulation and are rated for ambient temperatures
up to 85°C with no derating. This 25S Series is

Notes
1. Additional optional lead form, packaging and lead spacing requirements are subject to availability and to minimum
order requirements. Please contact factory for details.
2. Nickel Barrier Wire option (Suffix 'X2855')Standard parts use Tin-Coated Copper wire. Nickel Barrier Coated Wire
is available as an option.This is CopperWire with a flashing of Nickel, followed by a top coat ofTin.To order please
add suffix 'X2855' to end of standard part number. Contact factory for more details if required.
3. UltraMOV 25S have been qualified as type 1 application by UL1449 edition 3, which allows Permanant Connection
between the secondary of the service transformer and the line side of the service equipment overcurrent device,
as well as the load side, including watt-hour meter socket enclosures and intended to be installed without an
external overcurrent protective device.
