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.

 

2. 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).

Code description: SB1 SB2 stand for push button.(provided by users themselves) Number "1" "2" "3" stand for number of wiring terminals.

Voltage rating: AC50Hz 230V 400V DC 220V.

 

2) Wiring diagram of type CD motor-driven operation device (fitting AM1-400 630 800) seebelows (wiring diagram of the external accessories of the breaker in the dotted frame).

Code description: SB1 SB2 stand for push button. (provided by users themselves) "X" stands for line connection terminals Voltage rating: AC50Hz 230V 400V DC 220V.

 

Rotary handle operation device.

The mechanism is used in moulded case circuit breaker to operate the draw-out panel. Power distribution 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" model square handle , the other is "B" model round handle.

3.2 Release pattern and accessories code.

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

 

Under-voltage release.

Wring diagram of the under-voltage module connected externally (the internal accessories in the dotted frame)Ue: AC50Hz 230V, 400V.

ms1re

When the operation voltage is 35%~70% of the rated voltage, the under-voltage release should make the breaker trip correctly.When the operation voltage is 85%~110% of the rated voltage, the under-voltage release should make the breaker close.In case of the operation voltage less than 35% of the rated voltage, the under-voltage should prevent 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.

ms1ps

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.
