COOPER POWER
SERIES
Arrester/flipper fuse combinations
General
Eaton's offers a wide variety of arrester/flipper
fuse combinations in its Cooper Power™ series
product line. Flipper fuse assemblies can be
ordered as a stand alone kit, or in combination
with a variety of distribution-class surge arresters.
These packages combine the functions of a
transformer mounted arrester and an open
link fuse assembly to provide users effective
overvoltage and overcurrent protection with a
minimum of pole­-top hardware.
Lightly loaded distribution systems with low
available fault currents are ideal locations for these
combinations. Current ratings of the flipper fuse
assembly include a continuous current rating of
50 A and an interrupting rating of 1200 A.
Arresters in these packages can be ordered with
silicone rubber (UltraSIL®) or porcelain housings,
while the internal design is gapless MOV
(VariSTAR®). Additionally, arresters are available in
normal- or heavy-duty distribution classifications.
With these multiple options, customers can order
an arrester/flipper fuse combination to fit almost
any system application.
All surge arresters supplied in these combinations
have been tested to, and meet or exceed, all
the requirements of the latest revision of IEEE
C62.11™, “IEEE Standard for Metal-oxide Surge
Arresters for Alternating Current Power Circuits”.
Graphics on the left show the arrester/flipper
fuse combination with an UltraSIL silicone rubber
housed arrester and on the right a porcelain
housed arrester. Below are the component parts,
AM21A1. Please note, fuse links are not included
with these packages. For information on available
fuse links, see Catalog Data CA132008EN Edison

Flipper fuse kits
Customers who need a flipper fuse kit without an arrester can order
this kit separately. The kit includes both flipper arms (for attachment
to the arrester and the transformer bushing) and an optional
insulated wildlife protector for the transformer bushing. Refer to
Figure 3 for a view of the complete flipper fuse kit (including the
optional wildlife protector) and Table 1 for a listing of the correct
catalog numbers for ordering these kits.
