4.2.2 Circuit-breaker
(Figures 3/2 and 4/1)
Charging the stored-energy spring system
• On breakers with charging motors, charging is
carried out automatically. If the charging motor
should fail, the charging procedure can be carried
out or completed by hand.
• On breakers with manual charging systems, door
opened and withdrawable part in disconnected
position, insert the charging lever (128) into the
socket (13.6) and pump for approx. 25 strokes
until the charged condition is indicated. When
the charging condition is reached, the charging
mechanism is auto matically disengaged, and any
further strokes of the lever have no effect.
Meaning of the charging condition symbols:
Discharged
Charged
Opening and closing the circuit-breaker:
• With the withdrawable part in the service position,
on and off switching operations should only be
carried out with the doors closed.
• Operate the local or remote electrical control.
• Observe the switch position indicator. The swit
-
ching operation counter (13.5) for the circuit-
breaker is automatically incremented by one unit
with each operating cycle.
