If the same power supply used for the closing and undervoltage releases and the circuit-breaker required to
close automatically when the auxiliary power supply comes back on, delay must introduced between
the undervoltage release accept signal and the energizing the closing release. (K51/Zin, K51/Zout, K51/Gzin and K51/Gzout) are not wired. The coils can controlled directly from contacts K51/YO
and K51/ with maximum voltages 110-120 and 240-250 AC. The circuit-breaker can only close when the release energized (there is
a mechanical lock closing). This may achieved using an
external circuit comprising permanent make contact, the contact shown fig. The shield must be
earthed the selectivity input side.
