UltraSIL® polymer-housed VariSTAR™
station-class surge arresters
General
Eaton has set a new standard of excellence for
polymer-housed station-class surge arresters with
its Cooper Power™ series UltraSIL® polymerhoused surge arresters. Enhancements in arrester
design allow Eaton to offer increased cantilever
strength and improved energy handling capability.
Eaton’s Cooper Power series VariSTAR® Type US,
UH, and UX station-class arresters incorporate
the industry recognized superior silicone rubber
housing with a unique high creep alternating shed
profile designed to withstand the most extreme
environments. The “standard” silicone rubber
housing is designed with a minimum specific
creepage distance of 31 mm/kV L-L, which meets
category IV (Very Heavy) pollution level according
to the IEC standard. This housing is applied over a
gapless MOV internal design.
Types US, UH, and UX arresters meet or exceed
the requirements of IEEE Std C62.11™-2005
standard including Short Circuit Tests performed
in accordance with IEEE Std C62.11a™-2008
standard.

Construction
Features
The unique construction of UltraSIL polymer-housed Type US, UH,
and UX station-class arresters begins with world class Metal Oxide
Varistor (MOV) disks produced at our dedicated manufacturing
facility in Olean, NY. By manufacturing our own disks we maintain a
strict quality control over the entire pro­duction process, from initial
raw material inspection to final physical and electrical testing of
each disk. In addition, by controlling the manufacturing process of
both disks and arresters, we achieve the optimal combination. Eaton
produces MOV disks of unsurpassed quality through continuous
improvements in disk formulation and manufacturing technology.
The end result is a long history of in-service use with outstanding
durability and protective capability.
The UltraSIL silicone rubber housing was selected for its superior
insula­tion performance as compared to other polymeric housing
materials. Long term environmental testing has verified the lifetime
performance advantage that silicone rubber provides.
Arrester production begins by stacking glass-collared MOV disks in
series with aluminum end electrodes. Our proprietary process wraps
the assembly with a woven fiberglass-reinforced epoxy composite.
When cured, the arrester module is capable of withstanding heavy
electrical and cantilever load conditions.
The UltraSIL silicone rubber housing utilizes an inter­ference fit and
is bonded onto the internal module to form a solid, void-free, highdielectric strength insulation system. Once assembled, each arrester
must pass a strict series of electrical tests to insure the highest level
of in-service performance.
The silicone rubber housing results in lighter weight than similarly
rated porcelain-housed arresters. The silicone rubber housing is less
sensitive to physical damage than porcelain. Also, when compared
to other polymeric housing materials, silicone rubber generates
significantly lower external power losses under contaminated
conditions.
Independent laboratory tests have verified the superior water
repellent behavior of silicone rubber, which is responsible for the
lower external power losses, higher resistance to UV degradation
and surface tracking, superior performance in contaminated
environments, and other important insulating properties. Also,
UltraSIL silicone rubber has been proven to be non-flammable and
self-extinguishing per UL 94V0 standards.
The basic silicone rubber-housed arrester can be customized with
a variety of terminal and mounting options which allow users to
select the features that meet their application needs. Customers
who require longer creepage housings can easily select a different
housing option through the catalog numbering system. See pages
14-15 for a complete list of available options.
Operation
The operation of the UltraSIL polymer-housed Type US, UH, and UX
arrester is typical of gapless metal oxide arresters. During steadystate conditions, line-to-ground voltage is applied con­tinuously
between the line and ground terminals of the arrester. When surges
occur, the arrester immediately limits, or clamps, the overvoltage
condition by conducting the surge current to ground. After passage
of the surge, the arrester returns to its initial state, conducting
minimal leakage current. This minimal leakage current (which is
primarily capacitive, with a small resistive component) can be
withstood on a continuing basis.
The UltraSIL polymer-housed Type US, UH, and UX arresters easily
surpass the minimum fault current withstand requirements for
station-class arresters as defined in IEEE Std C62.11a™-2008
standard (40 kA). These arresters have been tested and shown to
withstand fault currents of 63 kA. During these tests, the silicone

rubber housing ruptures without expelling internal parts.
UltraSIL polymer-housed Type US, UH, and UX arresters are ideal
for protection against repeated high energy switching surges and
provide reliable protection for substation equipment, capacitor banks,
multiple lines, and cable circuits. They are also ideal for applications
where lighter weight and shorter heights (when compared to
porcelain-housed arresters) are critical.
Design testing
The housing, internal components, and hardware of an arrester must
work together as a system. This system must stand up to years of
service while being subjected to a wide range of environmental and
electrical stresses. To ensure a superior level of performance, both
arrester components and finished arresters have been subjected
to a series of tests that accurately represents years of exposure to
actual field conditions. This testing far exceeds the requirements of
industry standards.
The UltraSIL polymer-housed arrester has also met or exceeded
all require­ments for station-class arresters as defined by IEEE
Std C62.11™-2005 standard. Reference CP1121 UltraSIL PolymerHoused VariSTAR Type US, UH and UX Station-Class Surge Arresters
Certified Test Report.
The Type US, UH, and UX arresters are USDA’s Rural Utilities Service
(RUS) Section ae approved, meeting or exceeding all RUS technical
specification and workmanship.
Production tests
Eaton has implemented a complete production test program to
ensure a quality product. Each MOV disk is subjected to a series of
electrical tests to maintain quality. We also perform additional tests
on every MOV disk batch. Listed below are the tests performed on
the MOV disks:

General application recommendations
The rating of an arrester is the maximum power-frequency lineto-ground voltage at which the arrester is designed to pass an
operating duty-cycle test (as defined in IEEE Std C62.11™-2005
standard). Table 2 provides a general application guide for the
selection of the proper arrester rating for a given system voltage
and grounding configurations as outlined in IEEE Std C62.22™2009 standard, which is the application guide for metal oxide surge
arresters.

Under fault conditions and other system anomalies, higher
than normal voltages can be imposed upon an arrester. With an
improper arrester selection, these abnormal system voltages can
cause an arrester to fail. To help ensure that the proper arrester
is selected, Eaton’s application engineers are available to make
recommendations.

The following information is normally required:
Ordering information
1. Maximum system operating voltage.
Table 3 includes the shortened catalog numbers for UltraSIL
polymer-housed Type US, UH, and UX arresters. The arrester
represented by the shortened catalog number is configured with the
standard configurations shown in Table 10. The shortened catalog
numbers shown in Table 3 represent the same catalog numbers
shown in Table 9. For example, catalog number USAA060A from
Table 3 represents the same catalog number USAA060048A2845A11
from Table 9. Eaton offers other options that allow customers to
select specific features they desire. Options on housing sizes
(creepage length), hardware, and mounting options are available and
defined in Table 10. This table allows customers who prefer options
different from those in our standard Table 9 configuration to develop
a catalog number which provides the unique features they desire.
For additional assistance please contact your Eaton representative.
2. System grounding conditions;
A. For four-wire circuits, grounding conditions depend upon
whether the system is multi-grounded, whether it has
a neutral impedance and whether common primary and
secondary neutrals are used.
B. For three-wire circuits, grounding conditions depend upon
whether the system is solidly grounded at the source,
grounded through neutral impedance at the source transformers or ungrounded.
3. Available Fault Current.
4. Maximum line-to-ground voltage and overvoltage duration during
fault conditions.
Contact your Eaton representative to have your individual system
application needs reviewed.
Temporary overvoltage (TOV) withstand
ability
The UltraSIL polymer-housed Type US, UH, and UX arrester’s ability
to withstand 60 Hz overvoltage conditions (TOVs) is shown in Figure
2. The graph illustrates the time an arrester can survive a voltage,
and recover, without going into thermal runaway, for a given voltage
magnitude (expressed in Per Unit of arrester MCOV).
The graphs in Figure 2 illustrate TOV withstand ability, with and
without prior duty. The prior duty curve is based upon absorption of
rated energy (Refer to Table 1 — Single Impulse Rating) immediately
preceding application of the overvoltage.
Mounting information
The standard base of the UltraSIL polymer-housed Type US, UH, and
UX arresters is designed for mounting on 8.75” or 10” diameter bolt
circle patterns. The three slotted mounting holes are spaced 120°
from each other and are designed to handle 0.5” diameter bolts.
Mounting hardware (bolts, nuts, and washers) is not in­cluded with
the arrester. See Figure 3 for mounting base details. An inherently
strong design allows these arresters to be mounted in a variety of
ways. They can be mounted vertically, with attachment at the base,
or suspension (underhung) mounted. Eaton offers more flexibility
for customers to mount arresters in the field. Station-class arresters
can be configured in the underhung position (suspension mount) at
the plant or with a unique new option assembled in the field in the
underhung position*. UltraSIL polymer-housed station-class arresters
can also be horizontally mounted through 120 kV.
* Field base conversion for Types UH and UX only.
