Note: 6A no thermal protection 

The N-pole of four-poles breaker is sifed at the right side of the product has four types: 

Type A: No current trip-lease on N pole which making all the time, not closing and opening with the other three poles.

Type B: No 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 frip-release which making all the time not closing and opening with the other three poles.
