Protection level: IP20;
Weight: Approximately 500g.

These releases are connected with current transformers (three or four according
to the number of conductors to be protected), which are positioned inside the
circuit-breaker and have the double functions of supplying the power necessary
to the proper functioning of the release (self-supply) and of detecting the value
of the current flowing inside the live conductors; therefore they are compatible
with alternating current networks only.
The signal coming from the transformers and from the Rogowsky coils is
processed by the electronic component (microprocessor) which compares it
with the set thresholds. When the signal exceeds the thresholds, the trip of the
circuit-breaker is operated through an opening solenoid which directly acts on
the circuit-breaker operating mechanism.
In case of auxiliary power supply in addition to self-supply from the current
transformers, the voltage shall be 24 Vdc ± 20%.
Besides the standard protection functions, releases provide:
– measuraments of currents (Ekip LSI/LSIG + Ekip COM, Ekip M LRIU + Ekip COM,
PR222, PR232, PR331, PR121);
– measurament of currents,voltage,frequency,power,energy,power factor
(PR223,PR332,PR122) and moreover for PR333 and PR123, the measurement of harmonic distortions is available;
– serial comunication with remote control for a complete management of
the plant (Ekip LSI/LSIG + Ekip COM, Ekip M LRIU + Ekip COM, PR222,
PR223, PR232, PR331, PR332, PR333, PR121, PR122, PR123).
