4  Advantages
1) The arc-extinguish chamber is on the upper part and the mechanism is on the lower part. This structure is convenient for debug.
2) Complex insulating structure using air and organic material; Compact dimension and small weight.
3) Vacuum arc-extinguish chamber of Cutler-Hammer Company (USA) and domestic ZMD are both applicable for the VCB. Both two kinds of chambers extinguish arc by vertical magnetic field and featuring with low cut-off and good on-off capability with asymmetry.
4) Simple spring operation mechanism is free from maintenance within 10000 times of operations.
5) Lead-screw propeller, easy and stable operation and good self-locking capability.
