Bay-O-Net Fuse Cross Reference

Time:2023-12-13   Author:As Beam   Browse:

The Bay-O-Net fuse provides safeguarding for both single- and three-phase transformers. The Bay-O-Net assembly merges the convenience of hotstick operation with the security of deadfront construction. It's utilized alongside an isolation link to prevent line workers from inadvertently closing into a fault while replacing a blown Bay-O-Net link.


Ideal for incorporation into a two-fuse protection system alongside a current-limiting backup fuse, the Bay-O-Net fuse handles secondary faults and overload currents, while the current-limiting fuse tackles high-level faults. These two fuses are series-connected and coordinated to ensure that the current limiting fuse only triggers in case of internal equipment failure. When the Bay-O-Net fuse isn’t used in series with a current limiting fuse, an isolation link is necessary.

Despite being cost-comparable to internal cartridge fuses, Bay-O-Net fuses offer the advantage of field-replacement. They can be easily synchronized with upstream devices, enhancing their adaptability. When employed in series with a Bay-O-Net type fuse, an isolation link provides supplementary protection during both refusing and switching operations. Additionally, the oil-immersed current sensing weak link cartridge fuse serves as an internal, weak link expulsion fuse.
