The Bay-O-Net system is the standard protection for padmount and submersible transformers: the fuse holder lets crews pull and replace the expulsion fuse from outside, without opening the tank or taking the transformer out of service. The expulsion fuse is commonly called the cartridge fuse.
We carry the complete Eaton Cooper Power Series system: 23 and 38 kV fuse holders (with and without flapper valve), dual-sensing fuses (tripping on both current and oil temperature), current-sensing, dual-element and high-ampere fuses, and the isolation link fuses installed in series with the expulsion fuses.
With flapper valve (prevents oil spill on removal) or without; silver-plated versions for high-ampere fuses.
Sense both current and oil temperature, protecting against sustained transformer overload.
Sense current only, for coordination schemes that do not require temperature tripping.
Two elements to coordinate overload and short-circuit protection in distribution networks.
High-ampere fuses from 65 to 200 A and isolation link fuses installed in series with the expulsion fuse.
