ABB_RREC_79
Multi-shot auto-reclose sequencer with proven breaker opening, per-shot dead times, a pulsed close, reclaim supervision and a lockout that only a separate reset releases.
When to use it
Use ABB_RREC_79 when an overhead feeder or line breaker should be re-closed automatically after a protection trip, because most overhead faults are transient, and the scheme must lock out rather than keep re-closing onto a fault that is still there.

Supervised control write
ABB_RREC_79 commands a real actuator. It is written to sit underneath your own interlock, permissive and protection logic — not to replace it. Commission it as you would any control block you wrote yourself.
