    Classification of mccb:


    It is sorted into three-pole and four-poles according to product pole number. The type for neutral pole of four-pole products is sorted into four kinds:


    Type A:N pole can’t be installed with over current tripping element , and it always switch on, can’t switch on and switch off together with other three poles.


    Type B:N pole can’t be installed with over current tripping element, it can switch on and switch off together with other there poles.


    Type C:N pole can be installed with over current tripping element, and it also can switch on and switch off together with other three poles.


    Type D: N pole is installed with over current tripping element, and it always switch on, can’t switch off together with other poles.
