Figure 3/10: Circuit
breaker wiring
diagram with
conventional
equipment for
VD4X-U.
Shown with the spring energy store in the
discharged state. The wiring diagram comprises
the basic components and all further equipment
options for the various VD4X types. The scope
of equipment possible within an individual type
series is listed in the relevant switchgear list, and
the equipment fitted in each individual case can
be found in the order documentation.
Note
Shunt releases and blocking magnets are fun
damentally wired with rectifiers (e.g. magnet
holder 34 with integrated rectifiers -V1, -V2, -V3
and -V9).
Rectifiers function as free-wheeling diodes if
d.c.-supply. No use of Figure 3/8, when -Y4 and
-Y7 required.
-S1 Auxiliary switch on spring charging
mechanism
-S2 Auxiliary switch on blocking magnet
-RLE1 (optional)
-S2-1 Auxiliary switch for push button
interlocking (optional)
-S3 Auxiliary switch on switch shaft
-S4
-S5
-S7 Wiping contact for circuit-breaker (≥35
ms tripped indication) (optional)
-S10 Auxiliary switch at mechanical close
push button (optional)
-Y1 Closing block magnet with rectifier -V1
(optional)
-Y2 1 st shunt release off with rectifier -V2
-Y3 Closing release with rectifier -V3
-Y4 Undervoltage relay with rectifier -TB6
(optional)
-Y7 Inductive overcurrent relay with
rectifier -V7 (optional)
-Y9 2 nd shunt release off with rectifier -V9
(optional)
-M0 Charging motor
-K0 Antipumping relay
-R0 Resistor for antipumping relay
1) If the fitting is without blocking magnet -Y1 bridge between
-S3:42 and-Y3:C1. Opening contact -S3:22 will be connected
same as other contacts.
See page 28 for comparison of VDE/IEC designations.
