Note:
1. The current state of the circuit breaker is de-energized, disconnected, connected, no energy stored;
2. Status indicator light, button switch and communication equipment are provided by users, and the dashed part shall be
wired by users;
3. if the rated working voltages of Q, F, B, M and controller are not the same, please connect to the rated voltage of control
power supply;
4. In order to ensure the reliable operation of the controller, 1# and 2# need to be connected to auxiliary power;
25#、26#——Select one from N pole transformer output（3P+N） ， leakage transformer output and remote reset input.
5.
earth current type ground protection or leakage protection is additionally selected, but external transformer is not connected,
then terminal 25# and 26# should be short connected;
6. The secondary terminal wiring is only suitable for the 0.5~1.5mm
recommended; pay attention to adopt the appropriate conductor;
7. All the signal units are passive signals; users can choose S1, S2, S3 modes as required;
8. The user needs to select the signal unit to achieve the "four remotes" function, while the power supply module and relay
module are optional.
9. There is a control circuit inside the shunt release and closing electromagnet, which can be powered on for a long time, and
the power-on time is more than 200ms. Users should not connect them in series with the circuit breaker itself.
Auxiliary switch contacts;
10. When the voltage closing device is selected, the electrical wiring diagram of the closing electromagnet and the
undervoltage release controlled by the voltage station is shown in the attached drawing, i.e. electrical wiring diagram of
voltage closing device;
11. The voltage-check closing device is a special accessory for NDW3-2500.
12. The wiring terminals number of NDW3-4000 product four normally open and four normally closed auxiliary contacts is 45~60.
