Bay-O-Net Fuse Links
Current Sensing Bay-O-Net Fuse Link |
 |
| GENERAL |
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. If the Bay-O-Net fuse will not be used in series with a current-limiting fuse, an isolation link is required. 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.
Dual Element Bay-O-Net Fuse Link |
 |
| GENERAL The Cooper Power Systems Dual Element Bay-O-Net Fuse Link is used in Bay-O-Net fuse assemblies to protect distribution apparatus from dam aging currents and to protect distribution systems from failed apparatus. Dual element links sense not only secondary faults, excessive load currents and transformer faults, but also transformer fluid temperature. They will limit long-term transformer heating caused by overloads and high temperature environments. |
|
APPLICATION
Bay-O-Net fuses can be used on single-phase conventional and self-protected distribution transformers and on three-phase equipment. 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 equipment failure. If the Bay-O-Net fuse will not be used in series with a current-limiting fuse, an isolation link is required.

Dual Sensing Bay-O-Net Fuse Link
GENERAL
The Cooper Power Systems High Ampere Overload Bay-O-Net fuse link is used in the Cooper Power Systems silver-plated Bay-O-Net assemblies to protect distribution apparatus from damaging currents and to protect distribution
systems from failed apparatus.
High ampere overload links provide better heat dissipation when used at higher load current levels. These lower
operating temperatures will extend Bay-O-Net applications to larger kVA units.
APPLICATION
High current overload Bay-O-Net fuses were designed to allow the fusing of larger kVA distribution transformers, both single-phase and three-phase. Its ideal use is in a two-fuse protection scheme with a current-limiting backupfuse. 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 currentlimiting fuse operates only upon internal transformer failure.
If the Bay-O-Net will not be used in series with a current-limiting fuse, an isolation link is required. The High Ampere Overload Bay-ONet fuse is an integrated fuse link and cartridge design specially engineered to reduce operation temperatures. The Bay-O-Net design allows the integral (link) cartridge to be easily field replaceable.
High Ampere Overload Links should only be used in silver-plated Flapper Bay-O-Net assemblies in order to ensure the intended operating characteristics.

GENERAL
EL Bay-O-Net fuse assembly from Cooper Power Systems is used to mount the ELS current-limiting fuse in fluid-filled distribution apparatus. The fuse assembly provides the operating convenience of Cooper Power Systems versatile Bay-O-Net expulsion fuse with the energy-limitingcapabilities of the current-limitingfuses.
The outer housing, inner holder and handle are made of high strength thermoplastic for application on high-voltage systems at elevated temperatures. An arc follower attached to the lower end of the fuse aids loadbreak switching.
