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.
Protection Characteristic
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).
