Ground TCC Curve (OFF, TAP, MAIN) or (OFF, U1, U2, U3, U4, U5, C1, C2, C3, C4, C5
See Notes 1 and 2
For CoordinatingTap Curves:
Minimum Pickup (Amperes) (50, 65, 80, 100, 150, 200, 250, 300, 350, 400)
For CoordinatingMain Curves:
Minimum Pickup (Amperes) (100, 150, 200, 250, 300, 350, 400)
For Curves U1U5 and C1C5:
Minimum Pickup (Amperes) (50 – 400, 1 A steps)
TimeDial Multiplier U Curves (0.5 – 15.0, 0.1 steps)
TimeDial Multiplier C Curves (0.05 – 1.0, 0.01 steps)
For CoordinatingTap and CoordinatingMain Curves:
Instantaneous Pickup (kA) (OFF, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1, 2, 3, 4, 5, 6)
For Curves U1U5 and C1C5:
Instantaneous Pickup (Amperes) (OFF, 200 – 13200, 20 A steps)
For CoordinatingTap and U1U5 and C1C5 Curves:
Definite Time Delay (ms) @ 60 Hz (OFF, 32, 48, 64, 80, 96)
Definite Time Delay (ms) @ 50 Hz (OFF, 40, 60, 80, 100, 120)
For CoordinatingMain Curves:
Definite Time Delay (ms) @ 60 Hz (OFF, 64, 80, 96, 112, 128)
Definite Time Delay (ms) @ 50 Hz (OFF, 80, 100, 120, 140, 160)
Note 1:
Ground settings are not displayed and are disabled if the
Trip
mode is set for
the
1-Pole Trip
setting or if the Phase TCC curve selected is either Espeed or Kspeed.
Note 2:
Ground curves can be selected to provide a different TCC curve than the phase
setting. However, when TAP or MAIN is used for the phase TCC, only MAIN and TAP TCC
curves can be selected for the ground TCC setting. When a U or C curve is selected for the
Phase TCC, only the U and C families can be selected for the ground TCC setting.
