Product Description

It has a rotating arc extinguishing method that utilizes the electromagnetic force generated by the current flowing in the main circuit of the switch to cut off the current, reducing the burden on the operating mechanism.

The shell is formed by hydraulic expansion with 1500 air pressures, with the smallest welding length and the strongest circular shape to withstand internal and external pressure, thus maintaining high accuracy and high quality.
