Note:6A no thermal protection

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

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

Thpe B:No current trip-telease on N pole which closing and opening with the other poles

TypeC:With current trip-release which closing and opening with the other three poles.

TypeD:With current trip-release which making all the time not closing and opening with the other three poles.

3.       Protection Characterictic

     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).
