Operation
The operating torque is less than 35 ft-Ibs (47 Nm). During
transformer assembly, it is recommended to operate the
switch one complete cycle (in each direction), after fluid fill.
Sectionalizing loadbreak switches rotate 360° in either
direction for alternate source selection. An externally-
installed index plate prevents rotation to positions other
than the one desired. The switch cannot be switched more
than one position without resetting the index plate.
A spring-loaded activating mechanism ensures quick
loadbreak action and positive contact engagement trough all
positions. Switching can be accomplished in less than one
cycle, and should be performed with a hotstick.
Using a clampstick leverage tool (P/N CS125UFLTOOL) with
an Eaton's Cooper Power series Fit-On™ head clampstick
provides operators with increased level of mechanical
advantage when performing switching operations.
When switching (with hotstick) from one position to the
next, (for example: in Figure 7 “line A & B” to position
“line A only”), the limit plate should be located on the pin
between the origin and the destination.
Turn hotstick handle, in a rapid motion, until switch has
fully indexed into the next position. If for any reason, the
switching operation cannot be completed with a single
motion, it is acceptable to relax, regrip the hotstick and
complete the operation by moving the switch handle in the
same direction
as the original effort.

N
Do not reverse the direction of the switching
operation before completing the rotation to the next
position. Reversing direction prior to completing the
rotation to the next position could jam the mechanism,
making the switch inoperable.
If the handle stops (jams) in a position between
the designated (marked) positions, stop switching
operation and consult the factory prior to
reattempting operation of the switch.

WARNING
The misapplication of the switch constitutes a potential
hazard to life and property. Accordingly, the user must
exercise due care in utilizing these instructions to assure
that the switch is properly applied.
