Bay-O-Net Fuse Assembly

Safe, efficient distribution transformer protection

The Bay-o-net Fuse Holder Assembly is an externally removable transformer fuse holder device and is designed for use in pad-mounted or subsurface distribution transformers filled with transformer oil. When installed with current sensing, dual sensing, or dual elements fuse wire in it, the Bay-o-net Fuse Holder Assembly will provide a safe and highly efficient protection for distribution transformers and distribution systems.

The assembly provides the ease of hotstick operation with safe deadfront construction. Removal of its fuse holder indicates the apparatus is electrically isolated, allowing convenient fuse inspection or replacement.

The Bay-o-net housing is clamped to the tank at an angle that permits convenient hotstick insertion and withdrawal of the fuse holder assembly. A flapper valve is equipped inside the housing, which closes when the fuse holder is removed. This results in minimal oil spillage from the transformer tank, increases safety to line personnel during fuse change out, and reduces the potential of environmental concerns.
