Maintenance
Safety measure
! DANGER
Maintenance, repair and subsequent conver-
sion work may be carried out only by specially
trained personnel in accordance with the
operating instructions and/or special
conversions instructions. Training and
information sessions for personnel can be
provided by the competent Siemens
department
before starting any work on V-breakers,
reference must be made to the local safety
regulations for high-voltage switchgear, e.g.
the five safety rules (DIN VDE 0105/07.83
Part 1, Item 9). Switch off the power supply
and then close and open the V-breaker by
hand ( V-breaker in open state "closing spring
discharged" indication visible).
Non-observation can result in death, severe
personal injure or substantial property
damage.

Servicing

Under normal operating conditions, the 3AH3 vacuum
circuit-breaker is maintenance-free. We recommend
nonetheless a regular visual inspection.

Cleaning

To ensure the insulating capacity, it is necessary that
the insulating components are clean. Insulating
components and external breaker parts must be wiped
with a damp cloth. Use only warm water with the
addition of a mild liquid household detergent as
cleaning agent.
! WARNING
Windings and terminals must not be touched
if the power supply has not been disconnect-
ed.
Non-observance can result in death or
serious personnel injury.
! CAUTION
All springs of the operating mechanism must
be relaxed and the vacuum circuit-breaker
be brought into the open state, "closing spring
discharged" indication visible.
Non-observance can result in personnel injury.
