Arc chute for moulded case circuit breaker XMQN-63
The mechanism of arc chamber is used to form a cavity to discharge gas outward,so the high-temperature gas can be discharged quickly, and the arc can be accelerated to enter the arc chamber. The arc is divided into many serial short arcs by metal grids, and the voltage of each short arc is reduced to stop the arc. The arc is drawn into the arc chamber and cooled by grids to increase the arc resistance.
