66KV Arc extinguishing Assembly
66KV Arc extinguishing AssemblyLow voltage power circuit breakers use some type of Arc Extinguishers (arc chutes or arc chambers) mounted above and around the main contacts to extinguish arcs in air (Figures 21 and 22). This leads to the name low voltage power air circuit breakers. Arc chutes, in some form, have been used to extinguish arcs for more than a half century.
