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.
If 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 0.5~1.5mm2 multi-strand soft wire or hard wire with the soft wire
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.
