frame, compact design frame sizes: type, type, type, type, type rated current of stm series a~ a feature : contact repulsion device (patented technology) the technical scheme adopted by the invention is: as shown in figure , the new contact device is mainly consisted of static contact, moving contact, shaft
, shaft , shaft and springs; when the circuit breaker is in the closed state, shaft acts on the right side of the spring angle; when the circuit breaker has a large fault current, the moving contact will be subjected to the electric repulsion generated by the current itself, and rotate with the center...
