Informational and Settings Screens
The TripSaver II recloser features a Sectionalizing function in both the 4-kA and
6.3-kA rated models. When enabled, a TripSaver II recloser will start its secondary
protection function—the Sectionalizing function—over a user-specied range of
fault currents when the source-side circuit breaker or recloser for whatever reason
trips faster than the TripSaver II recloser's TCC overcurrent protection. It will count
the number of operations of the source-side circuit breaker or recloser and will drop
open after a user-specied number of counts. The Sectionalizing Settings screen is
shown in Figure 106.

Cold Wakeup NR
The Cold Wakeup NR setting is congured when a separate curve is desired in response
to a cold wakeup of the TripSaver II recloser. See Figure 105. In most cases, this is a
slower curve. This setting will be used by the TripSaver II recloser when the MODE-
SELECTOR lever is in the Down position or when the recloser is in the R-NR mode. After
10 cycles, if a current above the Current, A setting is not detected, the Cold Wakeup NR
curve will revert to the Standard NR curve.
The Cold Wakeup TCC curve will not be used in a “post-fault” situation, where the
load is being picked up after the TripSaver II recloser has previously dropped open. In
those cases, the Post Fault Wakeup NR curve will be used. See Figure 104 on page 72.
If a Cold Wakeup NR setting is not required, set the TCC curve to the same settings
as the Standard NR setting.
