Minor overcurrent
If the measured load current reaches the set current limit, this is detected as a warning. The
main LED for the affected phase will flash orange and the set current limit LED will flash green.
The warning relay will issue a signal. The warning itself will be cleared once the cause of the
overcurrent has been resolved. Ongoing operation will not be stopped.
Minor overtemperature
If the temperature inside the hybrid switch exceeds 65°C, a warning is indicated. Main LEDs
will flash orange. The warning relay will issue a signal. The warning itself will be cleared once
®
OMUS cools down. Ongoing operation will not be stopped.
