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 otherthree 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 threepoles.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 cir-cuit breaker) and table 3 (motor protection circuit breaker).Table2
