Technical specifications
The withdrawable version of the circuit breaker/switch discon-
nector is intended for demanding industrial applications where
rapid exchange of the circuit breaker, frequent checking and
both visual and conductive disconnection of the circuit are
needed.
• The withdrawable version must be fitted with the following
connecting sets:
2 x 3VT9 500-4EF30, for front connection or
2 x 3VT9 500-4RD30, for rear connectionn
• For mounting withdrawable device to switchgear, use
3VT9 500-4SA40 installation bolts, see page 6/7.
Circuit breaker position
The withdrawable version of the circuit breaker has three posi-
tions:
1. inserted (connected position)
2. withdrawn (disconnected position)
3. removed
Main circuit
• To connect busbars and cable lugs, use 3VT9 500-4EF30 con-
nection set (front connection) or 3VT9 500-4RD30 (rear con-
nection).
• For connection using cables, it is necessary to use addition-
ally 3VT9 500-4EF30 or 3VT9 500-4RD30 connection sets.
• The way of connecting the main circuit must observe recom-
mendations (see page 6/11) as well as deionization space
(see page 6/13).
Auxiliary circuits
These are connected using 3VT9 500-4PL00 15-wire cables.
Circuit breaker accessories in plug-in version
The withdrawable version of the circuit breaker has the same
accessories as the fixed-mounted design.
States of switches 3VT9 500-4WL00 in withdrawable device
according to circuit breaker and arrestment positions
0 = contact open
1 = contact closed
3VT9 500-4WC00 specifications
For the wiring diagram of the circuit breaker in withdrawable de-
vice with accessories, see page 6/9.
3VT9 500-4WL00 position signalling
The withdrawable device can be provided with up to four
switches for signalling the circuit breaker’s switched-on position
(see table).
Advantages and enhanced safety for operator:
• Remote signalling of circuit breaker‘s switched-on position
(position of locking is not signalled)
• Checking of circuit breaker and accessories function in the
checking position
• Locking of withdrawable device against inserting circuit
breaker, locking of circuit breaker in withdrawn (checking)
position - locking by means of padlocks.
• Visible and conductive disconnection of the power circuit
• Easy exchange of circuit breakers in case of failure
