Note: 6A without thermal protection 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. 3. Protection CharacteristicThe thermodynamic release of a circuit breaker provides the feature of inverse time-delay, while the magnetic release is the instantaneous operation as shown on table 2(distribution circuit breaker) and table 3 (motor protection circuit breaker).
