Circuit breaker position logic
For automatic reclosure and circuit breaker test
Separate binary inputs comprising information on the position of the circuit breaker are available for the auto-
matic reclosure and the circuit breaker test. This is important for
•
The plausibility check before automatic reclosure (refer to Section 2.2 Automatic reclosure function
(optional)),
•
the trip circuit check with the help of the TRIP–CLOSE–test cycle (refer to Section 2.8.2 Circuit breaker
trip test).
When using 1

or 2 circuit breakers in each feeder, the automatic reclosure function and the circuit breaker
test refer to one circuit breaker. The feedback information of this circuit breaker can be connected separately
to the device.
For this, separate binary inputs are available, which should be treated the same and configured additionally if
necessary. These have a similar significance as the inputs described above for protection applications and are
marked with “CB1 ...” to distinguish them, i.e.:
