Universal trip time delay formula is given above, while special curve parameters are given on
the below table.
t Trip delay (s).
A A constant for the characteristic (s).
I Momentary current (A).
Is Set current threshold (A).
-).
B A constant for the characteristic (s).
TMS Time Multiplier Setting (-).
The image below shows the custom trip delay curves with TMS = 1.00. TMS can be set in the
range (0.025 - 3.2) for any protection function
