13.5.1.6.2.3 Time Dial Setting

The time dial setting for all the curves is from 0.05 to 15 with a step size of 0.05. However, the

following restrictions apply:

 The USA curves have an effective range of 0.1 to 15 (if the user specifies 0.05 it will be

rounded up to 0.1 for the calculations).

 The IEC curves have a range of 0.05 to 1. If set to a value above 1, the relay will use 1 for the

calculations.

13.5.1.6.2.4 Characteristic Curves

Time overcurrent units include seven characteristic curves:

 USA Moderately Inverse

 USA Inverse

 USA Very Inverse

 USA Extremely Inverse

 IEC Standard Type A (Inverse)

 IEC Standard Type B (Very Inverse)

 IEC Standard Type C (Extremely Inverse)

The seven characteristic curves are shown on the following pages.

13.5.1.6.2.4.1 USA Moderately Inverse TOC Characteristic
