DC110V 0.55A、DC220V 0.27A
Closing preparation indicating contact PF：
It is composed of a mechanical indicating contact and a conversion contact, which
can send the closing signal and indicate the conditions:
1. The circuit breaker is disconnected;
2. The circuit breaker has stored energy;
3. No continuous opening command
The wiring diagram is shown in Figure 4 (1600-4000 frame), figure 5 (2000-2500-
3200-6300 frame), and the dotted part is connected by the user
rated working current：AC-12 AC400V 3A、DC-12 DC220V 0.15A
（1600&4000AF）
rated working current：AC-12 AC250V 3A（2000&2500&3200&6300AF）
SWT1
Fault trip indication contact：（Only support 1600AF/4000AF）
Provide a set of fault signal output in case of electrical failure
second SWT2 can be installed
Res Remote reset contact：（Only support 1600AF/4000AF）
in case of electrical failure and the breaker is disconnected, the device can reset
the breaker fault locking device remotely
this contact is not compatible with the SWT2 fault trip contact
Connection (CE), separation (CD), test (CT) three position indicating contact：
Drawer type optional accessories: 1600 shell frame can provide 2 separation
indication contacts (CD), 1 test indication contact (CT), 3 connection (CE)
indication contacts; 4000 shell frame can provide 3 CDs, 3 CTS, 3 CE; but it
needs to be ordered separately, each number is shown in Figure 6
Three position indicating contact is installed on the draw frame to indicate the
position of the circuit breaker in the drawer seat
When the circuit breaker is in the connection position, the wiring diagram is
shown in Figure 5 (the dotted line part is self connected by the user); the three
position indication signals of multiple groups are shown in Figure 6
