Figure 2.10-1 shows the operate times for the four IEC IDMTL curves with a time multiplier of 1.
Figures 2.10-2 and 2.10-3 show the ANSI operate and reset curves. These operate times apply to non-directional
characteristics. Where directional control is applied then the directional element operate time should be added to
give total maximum operating time.
