Recloser curves
The C60 uses the FlexCurve feature to facilitate programming of 41 recloser curves. See the FlexCurve section in this
chapter for details.

 PHASE TOC 1

The phase time overcurrent element can provide a desired time-delay operating characteristic versus the applied current
or be used as a simple definite time element. The phase current input quantities can be programmed as fundamental
phasor magnitude or total waveform RMS magnitude as required by the application.
Two methods of resetting operation are available: "Timed" and "Instantaneous" (see the Inverse TOC Curve Characteristics
section earlier for details on curve setup, trip times, and reset operation). When the element is blocked, the time
accumulator resets according to the reset characteristic. For example, if the element reset characteristic is set to
"Instantaneous" and the element is blocked, the time accumulator is cleared immediately.
