EAFR-101C features

The EAFR-101C is a multipurpose arc flash protection relay that can

receive light from four different channels of light point sensors and

can be applied for variety of applications .  The EAFR-101C can be

used as a stand-alone relay or as part of a more complex arc protec

tion system through the binary bus .

Main features of EAFR-101C:

• (110-220) Vac / (125-250) Vdc  auxiliary  power  supply;

• (18-72) Vdc optional power supply;

• Four arc point sensor channels (S1. S2. S3. and S4);

• Six binary inputs (BI1. BI2. BI3. BI4. BI5. and BI6) nominal voltage

of 24 Vdc;

• Three normally open trip relay outputs with direct trip circuit rated

contacts (T1. T2. and T3);

• One normally open electronic lock-out trip relay with direct trip

circuit rated contacts (T2);

• Two 24 Vdc binary outputs (BO1 and BO2);

• One system failure relay, form C output (SF);
