In the case of a high-level fault condition, the Trip Unit will operate
whenever a complete RMS current value exceeds the trip level . For
this reason, the displayed value may be less than the actual RMS fault
current .

In the case of a very high fault current, the message "ORNG" (indicating
over range) appears because the Trip Unit cannot display the actual
value of the fault current .

Rating Plug is missing, damaged, or not well connected. If breaker is closed, it will trip, and
the instantaneous / override LED will light. If breaker is open, it will not close.
Protection functions still operate, but may be up to 12% out-of-tolerance. Replace trip unit
at first opportunity.
 Breaker tripped because phase current exceeded Short-Time Delay protection settings.
Breaker tripped because ambient temperature of microprocessor chip was excessive.
A trip test will begin as soon as you release the push to test button and "TEST message will
disappear. The breaker will trip, and the cause of trip is displayed.
A No Trip Unit test will begin as soon as you release push to test button, and the display
shows the elapsed time of test.


OverRlDe (Fixed Instantaneous) Trip is for type LS and LSG Trip Units
(no Instantaneous element), on circuit breakers whose Short-Circuit
current interrupting capability exceeds their Short- Time Current with-
stand capability (see Section 1 .1 .4) .

The values of the currents displayed after a TRIP event, are the values
at the time the TRIP operation was initiated . Although the magnitude
of a fault current, for example, can continue to increase after the TRIP
operation is initiated, those values of current occurring after the TRIP
operation is initiated, are not displayed .
