The use of an electromagnetically driven, convoluted electric arc in air along with PTFE ablation is described for the interruption of alternating currents. The approach is based upon electromagnetically attracting an annular atmospheric arc plasma column, during heavy current flow onto a PTFE cylinder containing a B field producing coil for enhancing PTFE ablation. Experimental results are presented to demonstrate the arc behaviour, the extent of the PTFE ablation and the occurrence of current interruption.
