Operating mechanism
The operating mechanism contains all the electrical and mechanical components re-
quired to close or open the vacuum circuit-breaker. Insulating operating rods
transfer the switching movements to the pole assemblies.
The operating mechanism is closed with a removable cover (20.1).
Operating and indicator elements
There are openings in the cover (20.1) for the operating and indicator elements.
Functions The CLOSE pushbutton (56.1) is used to close the vacuum circuit-breaker. The motor
immediately charges the closing spring. If the supply voltage for the motor fails, the
closing spring can be charged with a hand crank. There is an opening for this in the
cover (20.1), behind which you will find the hand crank coupling (57.2) of the gear unit.
You can use a key-operated locking device to avoid manual closing (59.3, only 3AE1).
Indicators The charge state of the springs is indicated by the spring state indicator (55.1). The
position indicator (56.3) shows the CLOSED or OPEN state. The operating cycle
counter (58) indicates the number of operating cycles. An operating cycle consists
of one closing and one opening.

be equipped with maximum one release of type 3AX11. The permissible combina-
tions of additional equipment as well as special versions can be found in the catalogue
HG11 or be obtained from the local Siemens representative.
Motor (-M1)
After the supply voltage is applied and if the closing spring is discharged, the motor
starts immediately and is automatically deactivated internally after charging has tak-
en place. Power consumption see table Fig. 26.
In the short charging time, the motor operates in the overload range. See Fig. 27 for
the rated current for the required motor short-circuit protection.
Note The motor protection devices are not included in the delivery of the vacuum circuit-
breaker and must be ordered separately.

If simultaneous electrical CLOSE and OPEN commands are continuously applied to
the vacuum circuit-breaker, it returns to the open position after being closed.
The function of the contactor relay (-K1) causes the vacuum circuit-breaker to pause
at this point until the CLOSE command is given again.
This prevents continuous closing and opening (pumping).

A further shunt release, transformer-operated release or undervoltage release can
be installed as a 2nd release.
2nd shunt release (-Y2) 3AX1101
The second shunt release (-Y2) is installed whenever more than one shunt release
is needed.
In this version, the electrical “open” command is passed by means of a magnet arma-
ture to the “OPEN” latch by release of an energy storage mechanism, thus opening
the vacuum circuit-breaker. This opening solenoid is not designed for continuous
operation. Any necessary varistors and rectifiers are integrated in the release.

Transformer-operated release (-Y4), (-Y5) 3AX1102, (-Y6) 3AX1104
The transformer-operated releases (-Y4), (-Y5) or (-Y6) consist of an energy storage
mechanism, an unlatching fixture and an electromagnetic system. If the tripping cur-
rent is exceeded (90 % of the transformer-operated release's rated current), the en-
ergy storage mechanism is unlatched, thus initiating opening of the vacuum circuit-
breaker module.
For use of the transformer-operated release, matching transformers are also
needed for matching, in addition to the main current transformers.
Power consumption for 0.5 A and 1 A 6 VA at 90 % of the transformer-operated
release's rated current and with open armature.

Undervoltage release (-Y7) 3AX1103
The undervoltage release (-Y7) has an electromagnet system that is always live
when the vacuum circuit-breaker is in the closed state. If the voltage drops below a
certain value, the undervoltage release (-Y7) is unlatched, thus initiating opening of
the vacuum circuit-breaker via the energy storage mechanism.
Random tripping of the undervoltage release (-Y7) is generally performed by an NC
contact in the tripping circuit, but can also be done with the aid of an NO contact by
short-circuiting the solenoid coil. If this latter method is used, the solenoid coil's
short-circuit current is limited by the built-in resistor.
The undervoltage release (-Y7) can also be connected to voltage transformers.
The undervoltage release (-Y7) automatically trips the vacuum circuit-breaker if the
rated supply voltage drops to an inadmissible value. Any necessary varistors and
rectifiers are integrated in the release.
Power consumption 20 W / VA
Note
The undervoltage release (-Y7) may only be operated with the series supplied
resistor (-R1).
Note
For switching operations (mechanical or electrical), the undervoltage release
3AX1103… must be connected to control voltage, as otherwise closing is not pos-
sible (see “Removing the transport securing device from the undervoltage release”,
page 57).

Locking devices
To lock vacuum circuit-breakers as a function of the switching position, the spring
charge mechanisms of the vacuum circuit-breaker can be equipped with a locking
device. This is also the case for vacuum circuit-breakers on switch gear trucks, in
withdrawable sections or with disconnectors.
Conditions The vacuum circuit-breaker must only be switched on in operating or disconnected
position. The operating or disconnected position is the position of the vacuum circuit-
breaker on the switchgear truck or withdrawable section in the switchgear. At the
same time, the vacuum circuit-breaker may be moved on the switchgear truck or
withdrawable section only when it is open.
Positions of th e vac uu m circuit-br ea ke r in th e sw it ch g e ar
Disconnected position The isolating distance between the vacuum circuit-breaker contacts and the switchgear
counter-contacts is attained fully.
Operating position The circuit-breaker is inserted fully into the switchgear and the vacuum circuit-break-
er contacts overlap completely with the switchgear counter-contacts.
Mechanical locking device (optional)
A sensing and actuation component (b) on the system side detects the operating
position (CLOSED/OPEN) of the vacuum circuit-breaker.
CLOSED switching
position If the vacuum circuit-breaker is closed, actuation of the system's interrogation and
actuation component (b) is prevented. A mechanical system in the switchgear truck
or withdrawable section reliably blocks movements of the circuit-breaker on the
switchgear truck or withdrawable section.
OPEN switching position If the vacuum circuit-breaker is open, the sensing and actuation component (b) on
the system side actuates, via the stroke (a), the vacuum circuit-breaker's mechani-
cal locking device and reliably blocks closing of the vacuum circuit-breaker.

Key-operated locking device 3AX1437 (optional, only 3AE1)
Electrical closing lock-out (-F1) 3AX1415 (optional, only 3AE1))
If the vacuum circuit-breaker is equipped with a mechan-
ical locking device, manual closing can be prevented
with the key-operated locking device.
Turning the key to the right/left or horizontally/vertically
locks the key-operated locking device.
The key can be pulled out in the locked position.
Note: The key-operated locking device protrudes 14 mm
from the cover.
Fig. 53 Key-operated locking device (59.3)
Instead of or in addition to the mechanical closing lock,
closing of the vacuum circuit-breaker can be prevented
with the electrical closing lock-out (-F1).
The electrical closing lock-out (-F1) enables operation of
the vacuum circuit-breaker if auxiliary voltage is availa-
ble and mechanically locks both manual closing and
electrical closing if auxiliary voltage is not available (po-
sition switch -S5).
Note: For mechanical or electrical circuits the electrical
closing lock-out 3AX1415 must be connected to the con-
trol voltage, otherwise no activation is possible.

DANGER
High-voltage - danger to life
Touching live parts causes an electric shock.
Do not touch live parts!
When performing work on the switchgear, de-energise it and earth it.
The work described in the following sections must only be performed when
the switchgear has been de-energised:
- Take safety measures to prevent reclosing.
- Observe industrial safety regulations.
- Ensure that the vacuum circuit-breaker is installed and commissioned
only by qualified personnel who are familiar with the operating instructions
and observe the warning notices.
WARNING
Risk of injury due to wrong transport means!
The use of incorrect transport can lead to the vacuum circuit-breaker falling and
injury to persons.
Observe weight.
Use means of transport suited to the requirements and load-carrying capacity.
The vacuum circuit-breaker must not fall over.
Sharp edges may cause injury.
WARNING
Danger of burns!
Touching the hot heater will cause burns.
Do not touch the heater before it has cooled off.
CAUTION
Danger of crushing at rotating and spring-loaded parts
Rotating and spring-loaded parts can move quickly through a manual release or a
remote tripping of the vacuum circuit-breaker. Fingers may be crushed if coming
into contact with rotating and spring-loaded parts.
Touching the openly accessible rotating and spring-loaded parts such as drive
shafts is to be avoided. Optionally, shaft covers for covering and protecting
against touching the exposed circuit-breaker shaft available and can be mounted
(see Chapter “Mounting the shaft covers”, p. 53).

Attachment in the switching cubicle
The vacuum circuit-breaker is delivered in the OPEN switching position and closing
spring discharged. Before installing the vacuum circuit-breaker remove the transport
aids (see “Unpacking” on page 6).
Check data Before installing the vacuum circuit-breaker in a switching cubicle, check the details
on the rating plate (see “Rating plate” on page 34) in order to avoid confusion.
Mounting position The SION® vacuum circuit-breaker can only be installed vertically (to the vacuum
interrupter), as an indoor withdrawable section and as an indoor fixed installation.
Note
For preliminary work, the vacuum circuit-breaker must be
secured against falling over,
placed onto a suitable support or
suspended from a crane to prepare for installation.
Note
Material damage due to incorrect operation!
If the SION® vacuum circuit-breaker is triggered manually with the cover removed
and the mechanical locking device actuated, the operating mechanism of the vac-
uum circuit-breaker will be irreversibly damaged. Any warranty claims are lost in
the event of such incorrect operation.
Use suitable means to prevent the SION® vacuum circuit-breaker from closing if the
cover has been removed and if the mechanical locking device has been operated.

Operation
Commissioning
Before commissioning, check the following points to ensure that the SION® vacuum
circuit-breaker is functioning faultlessly:
DANGER
High voltage - danger to life!
Touching live parts causes an electric shock.
Do not touch live parts!
Ensure that the vacuum circuit-breaker is operated only by qualified person-
nel who are familiar with the operating instructions and observe the warning
notices.
Check through all of the items on the checklist and ensure correct functioning
before commissioning.
CAUTION
Increased noise levels due to switching noise
Temporary noise levels above 85 dB (A) can cause damage to health.
Wear suitable ear protection.
Checklist Notes
Does the information on the rating plate (see page 34) match the ordering
data?
Ensure correct operating voltage.
If necessary, clean the vacuum circuit-breaker (details on this in section
“Cleaning” on page 72).
Check that screw connections are tightened securely.
Check terminal strip plug-connection for tightness.
If necessary, check and adjust the customer's devices.
Test switching without supply voltage
Charge the closing spring with the hand crank (see Fig. 121), then press
the CLOSE pushbutton and, once closing has been performed, press the
OPEN pushbutton.
Test switching with supply voltage
To perform test switching with the motor, switch on the supply voltage. The
motor starts up immediately and charges the closing spring. Check the indi-
cator for charge state of the closing spring (mechanically and electrically).
Electrically check through auxiliary switch S1 and position switch in both
end positions – operate the vacuum circuit-breaker to do so.
Check functioning of the closing solenoid Y9 and all available shunt
releases by operating them electrically.

First closing operation
If all functions have been checked and are ok, switch on high-voltage while observing
all of the safety regulations and operative requirements.
Charging the closing spring
If the supply voltage is applied, the closing spring is automatically charged by the
motor.
If an undervoltage release (Y7) 3AX1103 is present: has the locking screw
of the striker been shifted from position A to B (see “Removing the trans-
port securing device from the undervoltage release” on page 57)?
If mechanical locking is available: check if correct function of mechanical
locking is guaranteed as per IEC 62271-200.
WARNING
Do not commission the vacuum circuit-breaker if there are malfunctions.
If the malfunctions or the damage cannot be remedied, contact a sales represent-
ative or Siemens Service and, if necessary, send back the vacuum circuit-breaker.

WARNING
Risk of injury if hand cranks other than the original hand crank are used.
When the supply voltage is present, the motor immediately recharges the spring
after a closing operation. If the hand crank does not have a slip coupling, the hand
crank will also rotate.
To avoid injuries caused by the motor starting suddenly, the vacuum circuit-
breaker must be charged only using the original hand crank.
Operation
9229 0001 176 0G 69
2015-12-06
Hand crank If the supply voltage fails, the closing spring can be charged with a hand crank.
To do this, fit the hand crank onto the hand crank coupling through the opening
with the adapter pushed forward.
Turn clockwise until the spring state indicator changes over:
The adapter of the hand crank is designed in such a way that the hand crank
becomes uncoupled when the motor supply voltage returns.
Closing
Provided there is no lock-out due to a mechanical locking device, send the closing
command via the CLOSE pushbutton or the corresponding command element until
the vacuum circuit-breaker is closed, and shows and signals the CLOSED switching
position.
Change of the position indicator:
After closing and releasing the CLOSE pushbutton, if necessary, the closing spring
is immediately automatically charged by the motor and the symbol for “Closing
spring charged” becomes visible in the spring state indicator.
Change of the spring state indicator:

Opening
The opening spring is charged during the closing operation.
To open, send the opening command via the OPEN pushbutton or the correspond-
ing command element until the vacuum circuit-breaker is open, and shows and sig-
nals the OPEN switching position.
Change of the switching position indicator after electrical opening:
The spring state indicator does not change.
Discharging the closing spring
To discharge the closing spring:
Deactivate the supply voltage
on the vacuum circuit-breaker, actuate the OPEN, CLOSE and OPEN
pushbuttons manually one after the other.
This ensures that the vacuum circuit-breaker is open and the closing spring is
discharged.

Maintenance and servicing
Maintenance
The vacuum circuit-breaker SION® is maintenance-free under normal operating
conditions (up to rated current). We do, however, recommend you carry out regular
visual inspections. The maximum permissible mechanical operating cycle number is
10 000 (30000 operating cycles can be ordered as an option).
Preliminary work
Prior to starting work on the vacuum circuit-breaker, observe the local safety
regulations for high-voltage devices and the "5 safety rules" as per EN 50110-1.
Switch off the supply voltage and secure against reclosing,
on the vacuum circuit-breaker, actuate the OPEN, CLOSE and OPEN pushbut-
tons manually one after the other. This ensures that the vacuum circuit-breaker
is open and the closing spring is discharged.
Special operating conditions
If the vacuum circuit-breaker is operated under unfavourable conditions indoors
(heavy and frequent condensation, dusty air, etc.), we recommend cleaning the in-
sulating parts and possibly the outer parts of the circuit-breaker at shorter intervals.
DANGER
High voltage - danger to life!
Touching live parts is fatal or causes serious physical injury.
Before beginning maintenance work, note the five safety rules for high-voltage
equipment specified in EN 50110-1, namely:
Isolate from the power supply
Secure against reclosing
Verify safe isolation from the power supply
Earth and short-circuit
Cover or cordon off neighbouring live parts
WARNING
Crushing hazard!
Mechanical parts can move fast, even if they are remote-controlled.
Contact with mechanical parts or parts under spring charge may crush parts of
the body.
Do not remove covers.
Do not reach into openings.
Do not touch pole assemblies or circuit-breaker shafts.
WARNING
Danger of burns!
Touching the hot heater will cause burns.
Do not touch the heater before it has cooled off.

Cleaning
The insulating parts must be clean if their insulating capacity is to be guaranteed.
Rub insulating parts with a moist cloth.
As a cleaning agent, use only warm water with a mild, liquid household detergent
added and leave to dry.
Joints and bearings that cannot be disassembled must not be washed out with a
detergent prior to work.
Service life of the interrupter
If switching operations occur frequently under overload or short circuit, the service
life of the vacuum interrupters may be reached prematurely.
Accessories and spare parts
Replacing spare parts To ensure that the device operates reliably, spare parts must be replaced only by
trained and certified personnel.
Fig. 123 Accessories available for order
Always specify the vacuum circuit-breaker's type and serial no. (see “Rating plate”
on page 34) when ordering spare parts.
CAUTION
Risk of injury!
The vacuum circuit-breaker should be taken out of the switch cabinet or switchgear
for servicing.
Separate vacuum circuit-breakers from the control feed voltage or switch it off
and disconnect the low-voltage plug or clip connection.
