2.1 Arc protection relay EAFR-110PLV features
The EAFR-110PLV is a multi-purpose arc flash protection relay and
can be applied to a variety of applications. The EAFR-110PLV can be
used as a stand-alone relay or as a main relay of a more complex arc
protection system through the binary bus. The EAFR-110PLV may
also be used in conjunction with the Arc Quenching Device (AQD)
for the maximum level of arc fault protection.
The main features of EAFR-110PLV:
•
(110-220) Vac / (125-250) Vdc auxiliary power supply;
•
Three phase current inputs IL1, IL2, and IL3 (1A / 5A nominal);
•
One ground (earth fault) current input Ig (1A / 5A nominal);
•
Four arc point sensor channels
•
Two binary inputs (BI1, BI2) 24 Vdc;
•
Two high-speed semiconductor trip outputs (direct trip circuit
rated);
•
Two normally open (NO) trip relay outputs with direct trip circuit
rated contacts (T1, T2);
•
One binary output (24 Vdc);
•
One system failure relay, form C output (SF).
