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 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).

Rotary handle operation device
The mechanism is used in moulded case circuit breaker to operate the draw-out panel. Powerdistribution panel and supply box outside the panel by turning the handle ,and to ensure thedoor of panel would not be openned when the breaker being on. The hand-drive mechanism can be equiped with two types of operation, one is "A" modelsquare handle , the other is "B" model round handle.

According to user's demands, accessories could lead to direct wire outcoming or line wiringterminals could be added(please mark out in case of making order).

Under-voltage release

IMG_316



When the operation voltage is 35%~70% of the rated voltage, the under-voltage release shouldmake the breaker trip correctly.When the operation voltage is 85%~110% of the rated voltage, the under-voltage release shouldmake the breaker close.In case of the operation voltage less than 35% of the rated voltage, the under-voltage shouldprevent the breaker from closing.Note: Only the under-voltage release should be energized in advanced, the breaker could berecramped and turned-on, otherwise the breaker will be damaged.


Shunt release
Scheme of wiring(the internal accessories in the dotted frame)"K" is the slow motion switch normal-close contact connect the coil in series in the shunt release.It turns-on or turns-off voluntarily as soon as the breaker on or off.

IMG_317



Voltage rating: AC50Hz 230V or 400V, DC 110V 220VThe shunt release should make the breaker trip reliably when the operation voltage is 70%~110%of the rated control voltage.
