IRF
The IRF contact functions as an output contact for the self-supervision system of
the protection IED. Under normal operating conditions, the IED is energized and
the contact is closed (X100/3-5). When a fault is detected by the self-supervision
system or the auxiliary voltage is disconnected, the output contact drops off and the
contact closes (X100/3-4).
