IRF
The IRF contact functions as a change-over output contact for the self-supervision system
of the IED. Under normal operating conditions, the IED is energized and one of the two
contacts is closed. When a fault is detected by the self-supervision system or the auxiliary
voltage is disconnected, the closed contact drops off and the other contact closes.
Each signal connector terminal is connected with one 14 or 16 Gauge wire.
