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.
The 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).

Both MCB and MCCB are electrical line protection devices, but they also have some differences.The difference between a molded case circuit breaker and a miniature circuit breaker is that the electrica
[Circuit breaker knowledge] RCCB manufacturer will introduce the difference between the residual current circuit breaker and the residual current operated circuit breaker.
