Q) The second opening release may installed alternative the undervoltage release. Consult
this catalogue for information how make out order.
N) With PR122/DC and PR123/DC releases, the connections the zone selectivity inputs and outputs must made
with two-pole shielded and stranded cable (see user manual), more than 300 long.
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.Having
requested Uaux insulated from earth, one must use “galvanically separated converters” compliance with IEC
60950 (UL 1950) equivalent standards that ensure common mode current leakage current (see IEC 478/1,
CEI 22/3) not greater than 3. addition, the
indicator module PR120/K figures and cannot supplied.
S) Also available the version with normally-closed contact
V) fig.
B) The undervoltage release supplied for operation using power supply branched the supply side the circuit-
breaker from independent source. This may achieved using an
external circuit comprising permanent make contact, the contact shown fig. and time-delay relay. The shield must be
earthed the selectivity input side. 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).
E) MODBUS map available the RE1134001 document
F) The auxiliary voltage Uaux allows actuation all operations the PR122/DC and PR123/DC releases.5 mA, IEC 60364-41 and CEI 64-8.Notes
A) The circuit-breaker only fitted with the accessories specified the ABB SACE order acknowledgement. (K51/Zin, K51/Zout, K51/Gzin and K51/Gzout) are not wired
