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.

An igniteractivated blocking deviceblocks a fluid lineadapted to carry fluid. The blocking devicehas a housingdisposed about the fluid line, a pistonhoused in the housing, and an igniterthat when activated propels the pistonto block the fluid line. The ignitergenerates a shock wave to move the pistonto block the line. The pistoncrushes or squeezes a portion of the lineto close the line.
