Abstract Through experimental observation, this paper put forward that the arcing energy between the two gaps of a double-break MCCB may be unbalanced in breaking operation, and this may exert negative influence on the breaking performance of MCCB. Based on further study and experiment, back-commutation is confirmed to be the main cause for the unbalance issue; consequently by constraining of back-commutation, the balance can be approached through the means of reasonable designing.
