IRF

The IRF contact functions as an output contact for the self-supervision system of the
protection relay. Under normal operating conditions, the protection relay 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 contact X100:3-5 drops off and the
contact X100:3-4 closes.
