NOTES:
➀
Curves go to constant operating time above 30 X I
n
.
➁
Tolerance: ± 10% or 0.09 seconds, whichever is larger. Minimum operating trip time is 0.05 seconds.
➂
Tolerance: ± 10% or 0.09 seconds, whichever is larger (>1.5 x I
pu
). Minimum trip time is 2 power line cycles.
➃
For IECD, the Time Multiplier Tolerance is ±0.05 seconds.
