Eaton Current Sensing Bay-O-Net Fuse Link (cooper)

General
Eaton protects both distribution
apparatus from
damaging
currents and distribution
systems from
failed apparatus with its Cooper Power series
current sensing Bay-O-Net fuse link that is used
in Eaton's Cooper Power series Bay-O-Net fuse
assemblies (see Catalog CA132015EN Sidewall-
Mounted and Cover-Mounted Bay-O-Net Fuse
Assembly). They are used on single-phase conventional
and self-protected distribution transformers
and other apparatus rated through 500 kVA, and on
three-phase equipment
through 1500 kVA.
A Bay-O-Net fuse is ideal for use 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
equipment failure. (See Catalog CA132013EN ELSP
Current-Limiting Backup Fuse to order an ELSP
current-limiting backup fuse.) If the Bay-O-Net fuse
will not be used in series with a current-limiting
fuse, an isolation link is required. (See Catalog
CA132012EN Isolation Link.)
Bay-O-Net fuses are comparable
in cost to internal
cartridge fuses but have the advantages
of being
field-replaceable. Bay-O-Net fuses can easily be
coordinated
with upstream devices.
INSTALLATION
No special tools are required. A hotstick is used
to remove the Bay-O-Net fuse cartridge holder
from non-pressurized apparatus. The fuse cartridge
is then replaced, and the holder reinserted
using a hotstick. Refer to Service Information
MN132002EN Bay-O-Net Fuse Re-fusing
Installation Instructions for re-fusing instructions.
