Adaptive trip faulted circuit indicator Series 1547 specifications

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).
Reset Current Level:
1 5/8" sensor with U-lamination:	1.0A
2 3/16 " sensor with U-lamination:	1.5A
1 5/8" sensor with U-lamination:	2.0A
2 3/16" sensor with U-lamination:	3.0A
Operating Temperature :
Sensor:	-50° C to + 90° C
Indicator:	-40° C to + 85° C
Submergibility:	Tested to 30 feet.
Life Expectancy:	(1547A Series Flag-type) 20 + years.
Rated Battery Life:	800 hours of operation. Lithium cell, rated for 10 year life. (1547B Series LED-type; 1547C Series fiber optic type)
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.
