PERFORMANCE SPECIFICATIONS
Pickup: 5A CT: 0.50-16.0A
1A CT: 0.10-3.20A
Time Dial: TD=K=0 - 99 for 46 curve
TD=0.0 - 9.9 for all other curves
Time-Current Characteristics:
The following expression describes the inverse time current
characteristic for each curve:
T
T
= AD + BD + K = Time to trip
M
N
-C
T
R
= RD = Time for decaying reset
M

-1
where D = Time dial, M = Multiple of PU and A, B, C, N, K
and R are constants that govern the shape of each curve. The
protection engineer can set the constants for the P (programmable)
curve to achieve virtually any characteristic.
