An apparatus includes a laminated bus bar assembly with first and second bus bars and an intervening insulator layer. A surge arrestor (e.g., a metal oxide varistor) has a body mounted on the bus bar assembly and first and second terminals on first and second opposite sides of the body. In some embodiments, the body may be at least partially disposed in an opening in the first bus bar and the second terminal may be conductively bonded to a surface of the second bus bar that faces the insulator layer. In some embodiments, the second terminal may include a conductive stud passing through an opening in the second bus bar. The apparatus may include a spring clamp attached to the first bus bar and contacting the first side of the body to retain the body.

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.

An apparatus includes a plurality of semiconductor switches. A first bus interconnects first terminals of the semiconductor switches in a first chain and provides a first impedance between the first terminals of switches of the first chain. A second bus interconnects second terminals of the semiconductor switches in a second chain and provides a second impedance greater that the first impedance between the second terminals of the switches of the second chain. The apparatus may be implemented as a laminated bus assembly including respective overlapping conductor plates, wherein the second bus includes a plate having subregions defined by features, such as slots or grooves, that provide the second impedance.

A fused disconnect switch device includes a housing defining an interior volume, and a current path. An arc interruption assembly is located in the interior volume and includes a shell, and a conductor in electrical communication with the current path. At least one arc plate is located between the magnets and the conductor. The magnets cooperate to generate a magnetic field facilitating an interruption of a first arc between the conductor and the first side of the arc chamber and a second arc between the conductor and the second side of the arc chamber.

An improved triggered arc flash arrester includes a shield apparatus disposed within an interior of an evacuated envelope and includes a first shield element and a second shield element. A plurality of conductors are partially disposed within the interior and are separated from one another by a gap. A first element of the shield apparatus is situated adjacent the envelope and is structured to protect the envelope from damage due to the high temperature plasma that results from an arc across the gap. A second element of the shield apparatus is interposed between the gap and at least a portion of the first element and is structured to protect the at least portion of the first element from damage due to an arc across the gap.
