Sidewall-Mounted & Cover-Mounted Bay-O-Net Fuse Assembly

Cooper Power Systems Bay-O-Net Fuse Assemblies are used to protect transformers and distribution systems. They are designed for use in pad-mounted or subsurface distribution transformers filled with Envirotemp FR3 fluid, transformer oil or approved equivalent. The assemblies combine the ease of hotstick operation with the safety of deadfront construction.

The optional Flapper Bay-O-Net fuse assemblies (available as sidewallmounted only) include a flapper valve inside the housing which closes when the fuse holder is removed. This results in minimal oil spillage from the transformer tank which increases safety to line personnel during fuse changeouts, reduces potential of environmental concerns with oil spillage, reduces potential of oil contamination on the molded rubber elbow connections and reduces sensitivity to pad tilting.
