插入式限流熔丝 25kV Bay-O-Net fuse link

Eaton（Cooper）插入式限流熔丝 25kV Current sensing Bay-O-Net fuse link （4000353 Series）

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 SidewallMounted 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.

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.
