and iID residual current circuit breakers
Control

Operating principle
The ARA automatic recloser makes a number of attempts at reclosing depending on
the program chosen by the user.
The program includes the following settings:
b
b
A time delay before reclosing (TA).
b
b
A reinitialization time delay (TB).
b
b
A maximum number of reclosing attempts.
If, following these attempts, the fault is still present, the device places itself in
waiting for manual reclosing, or final remote reclosing (Y2).
