Circuit breaker closing and opening procedures

Circuit breaker operation can be either manual or electrical.
a) Manual operation for loading the closing springs
– Make sure that "O" (circuit breaker open) is displayed by the indicator
– Make sure that the indicator (6) is WHITE (springs unloaded)
– Repeatedly operate the lever (2) until the color of the indicator (6)
changes to YELLOW
b) Electrical operation for loading the closing springs
Electrical operation of the circuit breaker is possible when the following
accessories are installed:
– charging motor for automatic loading of the closing springs
– shunt closing release
– shunt opening release.
The charging motor automatically reloads the springs after each clos-
ing operation until the yellow indicator appears (6, Fig. 16). If there is
a power failure during the loading operation, the charging motor stops
and automatically continues with the spring loading operation once the
power returns. However, it is always possible to complete the reloading
operation in the manual mode.
