Operate Time Repeatability
Operate time is repeatable within
±
2% or 25 ms, whichever is greater.
Instantaneous Overcurrent
Pickup Range for Directional and Non-Directional Instantaneous Elements
Sensing Input Range 1 and 2:
2 to 100 Aac
Sensing Input Range 3 and 4:
0.4 to 20 Aac
Maximum Operate Time
Maximum operating times are derived while
stepping from a steady state (normal conditions)
to an overcurrent condition. When stepping from
an inhibit state, the maximum times are longer.
Table 1-1 lists the instantaneous operate times
for multiples of pickup.

Pickup Accuracy:
Within
±
5% of the defined pickup setting
Repeatability:
±
5%
Response Time:
Within 25 ms to a current reversal after fault inception
Power Supply
Relay operating power may be obtained from a wide variety of external sources. When ordering, any one
of five internal power supply types may be selected to match the operating power voltage level available
at your site. Available power supply types are listed in Table 1-2.
