Abstract
Systems, methods, and devices, for forming and using an arc flash mitigation switch are provided. In one exemplary embodiment, an arc flash mitigation switch includes a cylindrical shell having a first end cap and a second end cap located at either end of the cylindrical shell. A first and second conductive feed through extend through the first and second end cap, respectively, at one end, and at the other connect to a first and second electrode separated by a gap. The exemplary arc flash mitigation switch further includes a trigger feed through that receives a trigger current that commutates the external arc flash event into the arc flash mitigation switch, quenching the external hazard.
