Abstract: An electric fuse box or junction box assembly has a high voltage electric line cutter assembly inside an electric fuse box or junction box. The assembly has a box housing for connecting a plurality of electrical lines or connections to a power source. The housing has a pair of mounting stanchions for affixing the high voltage electric line cutter assembly with an electric current carrying busbar having a pair of stub ends. Each stub end of the busbar for carrying electric current from the power source to the plurality of electrical lines is secured to one of the mounting stanchions. Each mounting stanchion has an attachment platform for attaching and supporting the stub end of the busbar and an underlying chamber below the attachment platform for receiving exhaust gases generated when the high voltage electric line cutter assembly is activated.

Abstract: An electric line cutter device for high voltage busbars has a two-part housing, a piston, an igniter and a busbar. The upper housing includes a cylinder, cuboid or prism chamber. The lower housing also includes a cylinder, cuboid or prism chamber. The piston is contained inside one of either the upper housing chamber or the lower housing chamber. Upon igniting the igniter, the piston breaks a portion of the busbar moving the piston and the portion of the busbar into the opposite chamber thereby stopping the electric current flow. The piston is at least partially formed as an insulator to prevent electric discharge. The piston design together with chamber design includes integrated “squeeze areas” and “blow channels” for the appearing arc. A channel system outside or from inside the piston allow the pyro gases to push the arc plasma into a filter system to cool down the gases.
