Dual sensing fuse wire is used in Bay O-net fuse assemblies to protect distribution apparatus form damaging currents and to protect distribution systems from failed apparatus.
Dual sensing fuse wire not only secondary faults , excessive load currents and transformer fluid temperature. They will limit long-term transformer heating caused by overloads and high temperature environments
