Product Description
Eaton protects distribution apparatus from
damaging currents and distribution systems from
failed apparatus with its Cooper Power™ series
38 kV Bay-O-Net fuse link when used in Eaton's
Cooper Power series 38 kV silver-plated Bay-O-Net
assemblies. (See Catalog CA132015EN 23 kV and
38 kV Sidewall-Mounted and 23 kV Cover-Mounted
Bay-O-Net Fuse Assembly for information about
the fuse assembly).
Application
38 kV Bay-O-Net fuses were designed to allow the
fusing of solar, wind and other 24 - 38 kV rated
pad-mounted transformer applications.
Its ideal use is in a two-fuse protection scheme
with a current-limiting backup fuse. In this
arrangement, secondary faults and overload
currents are cleared by the Bay-O-Net fuse, and
high level faults are cleared by the current-limiting
fuse. The two fuses are connected in series and
are coordinated so that the current- limiting fuse
operates only upon internal transformer failure
(see Catalog CA132013EN ELSP Current-Limiting
Backup Fuse to order an Eaton ELSP currentlimiting
back-up fuse).
The 38 kV Bay-O-Net fuse is an integrated fuse
link and cartridge design specially engineered to
simplify re-fusing and prevent mis-installation. The
Bay-O-Net fuse design allows the integral (link)
cartridge to be easily field replaceable in a 38 kV
Bay-O-Net assembly.
38 kV links should only be used in Eaton's Cooper
Power series 38 kV silver-plated Flapper™ valve
Bay-O-Net fuse assemblies in order to ensure the
intended operating characteristics.
All 38 kV fuse links must only be used in series
with a 38 kV rated ELSP current-limiting backup
fuse or equivalent. 38 kV fuse links cannot be
used with an isolation link.
Installation
No special tools are required. A hotstick is used
to remove the Bay-O-Net fuse cartridge holder
from non-pressurized apparatus. The entire fuse
cartridge is then replaced. No field installation of
the fuse link into the cartridge is required. The
fuse holder is then reinstalled into the apparatus
using a hotstick. Refer to Service Information
