It provides stability in case of problems with disconnectors auxiliary contacts (stuck contacts or wiring problems). Ir relies on the feeder currents in the busbar.

Disconnectors positions are not required.

There is no selectivity using check zone. It's usefully because it prevents external faults to be considered as a busbar fault.
