Arc chute for MCCB XM3G-7 grey melanine board
The extinction of arc is due to the deionization of gas, which is mainly through recombination and diffusion. The arc chamber eliminates dissociation recombination. Recombination is the combination of positive and negative ions. Then they neutralized. In the arc chamber grid which is made of iron plate, the heat inside the arc can be rapidly exported, the temperature of the arc will reduce, the movement speed of ions can be reduced, and the recombination speed can be accelerated to extinguish the arc.

Copper plating and zinc plating have the same function in breaking current. But when plated by copper, the heat of the arc will make the copper powder run to the contact head, make it into copper silver alloy, which will cause bad consequences. Nickel plating perform well, but the price is high. During installation, the upper and lower grids are stagQQgered, and the distance between the grids is optimized according to different circuit breakers and different short-circuit breaking capabilities.
