An upper contact assembly is disclosed, which comprises a metal member, and an electrically conductive (EC) plate provided with an aperture thereon, a sheet metal spring, and a support unit are disposed in the accommodation space. Moreover, the sheet metal spring contacts with a bottom of the EC plate, and a protrusion block of the EC plate is exposed out of the metal member via the aperture. In addition, a hollow cylindrical (HC) conductor is vertically disposed on the top of the metal member, thereby being in contact with the protrusion block. As such, the HC conductor, the protrusion block, the EC plate, and the sheet metal spring are formed with an electrical transmission path therebetween, such that an electric wire is allowed to conduct a high-power electrical transmission through the ET path after being connected to a second end of the HC conductor.

A fuse cutout assembly cover including an insulator cover end for positioning over a cutout assembly insulator and including a shield end for shielding a cutout upper contact assembly. The insulator cover is constructed to receive a variety of insulator and cutout assembly configurations.
