| Adaptive
Trip Faulted Circuit Indicators - Series 1547 |
| Operating
Speed: |
Coordinates with
properly applied current limiting fuses, provided that the FCI trip-set
and the trip-release conditions are satisfied.
|
| Fault
Withstand Capability: |
25 kA
for 10 cycles per ANSI/IEEE 495-1986 |
| Operating
Current Range: |
The
FCI will operate from minimum reset current to 800 amperes for trip operation.
The maximum continuous current rating for the FCI is 800 amperes. |
|
Reset Function:
|
Resets to normal
indication according to unit selected from Ordering Information, Table
3 (Relay Delay).

| Line
Current: |
The FCI
adjusts to line current 40 - 60 seconds after the line current exceeds
minimum reset current. |
| Trip
Operation: |
A) Trip Enable Condition:
Occurs whenever line current increases by the rate of 100 amperes (or
greater) within 3 cycles
B) The FCI will
indicate trip only when the line current drops 1/2 amperes above the
minimum reset current within 40-60 seconds after the trip-set condition
occurs.
