2. The withdrawable part must only be movable
from the service position into the test/
disconnected position with the circuit-breaker
open.
Check this condition as follows:
• With the circuit-breaker closed, withdrawal
movement of the withdrawable part must be
blocked after only half a turn of the crank in
the anti-clockwise direction, and the travel
motor on motor-operated withdrawable parts
must not be capable of being switched on.
3. Closing of the circuit-breaker must only be
possible when the withdrawable part is in the
defined test/disconnected position or service
position.
The control wiring plug 36.1 must previously
have been inserted.
Check this condition as follows:
• It must not be possible to close the circuit-
breaker with the withdrawable part in any
position between the test/disconnected
position and the service position.
• Readiness for switching is established
electrically when the service position is
reached by auxiliary switch -S9 in the
withdrawable assembly switching over.
• For motion
position, the same enabling conditions apply
analogously, in this case by means of auxiliary
switch -S8 in the withdrawable assembly.
4. After failure of the power supply, the circuit-
breaker may only be operated manually in the
service position or in the test/disconnected
position:
a) Initially by pressing the OFF push-button 4, for
– up to 60 seconds for breaking currents up
to 25 kA.
– up to 120 seconds for breaking currents up
to 31.5 kA.
b) Manual emergency off switching using
operating lever 28 is possible beyond these
times.

5. Withdrawable parts with order-related blocking
magnet -Y0 may not be moved in case of control
power failure, or when there is no control power.
Do not forcibly move blocked withdrawable
parts! The blocking magnet -Y0 is only present
on manually operated withdrawable parts (Figure
9/30).
Releasing the blocking magnet -Y0:
• Remove front plate 1.1,
• Disengage blocking magnet -Y0 by pulling the
magnet armature,
• While doing so, turn crank 38 about one half
turn (either direction of rotation is permissible).
The blocking magnet is only active in the test
position and service position. In intermediate
positions it has no effect.

When parts are required, the serial number of the
relevant withdrawable breaker part or circuit-
breaker should always be quoted. Setting
instructions are to be requested separately.
