The N-pole of four-poles breaker is sited at the right side of the product has four types: 
Type A: Without current trip-lease on N pole which making all the time, not closing and opening with the other three poles. 
Type B: Without current trip-release on N pole which closing and opening with the other poles. 
Type C: With current trip-release which closing and opening with the other three poles. 
Type D: With current trip-release which making all the time not closing and opening with the other three poles.
