Up to five reclosing attempts can be included by parameter setting. The first attempt can
be single- and/or three phase for single-phase or multi-phase faults respectively.
Multiple autoreclosing functions are provided for multi-breaker arrangements. A priority
circuit allows one circuit breaker to close first and the second will only close if the fault
proved to be transient.
The autoreclosing function is configured to co-operate with the synchrocheck function.
