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 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 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 LASER-branded and is supplied in bulk packaging.

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 Copper Wire with a flashing of Nickel, followed by a top coat of Tin. 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.
