The durability of the TriSync capacitor switch was demonstrated by completing a minimum of 50,000 mechanical
operations after performing the Mechanical Life Test in accordance with IEEE Std C37.66™ standard. One operation is
defined as one close and one open operation.
Installation procedure
CAUTION
Personal injury . Sheds on epoxy encapsulation have
sharp edges . Wear protective gloves when handling the
unit . Failure to do so can result in cuts and abrasions .
T258 .1
Check-out procedure
1.
Check data plate .
Make sure that ratings on the data
plate are correct for the planned installation.
2.
Visually inspect the switch .
Visually inspect the
switch for any damage to bushing sheds, terminals,
tank, mounting frame or cables of trip handle.
3.
Install the switch .
Follow locally approved installation
procedures.
High-voltage connections
For 15 & 25 kV designs – TCSA, TCSB, TCSF
1.
Ground the switch .
Make the ground connection to
the ground connector located on the located on the
switch frame.
2.
Make line connections .
Connect the primary leads
to the switch terminals. The universal clamp-type
terminals accommodate AWG No. 8 solid through 2/0
stranded conductor.
3. Recommended torque levels for line and load terminal
hardware are 20–22 ft-lbs (27.1–29.8 N-m) not to exceed
30 ft-lbs (40.7 N-m).
For 38 kV designs – TCSE
1.
Ground the switch .
Make the ground connection to
the ground connector located on the switch located on
the switch frame.
2.
Make line connections .
Connect the primary leads to
the switch terminals. The switch terminal utilizes the
Standard NEMA 2 Hole termination, compatible lugs,
following recommended lug hardware and torque,
should be selected for customer wiring.
WARNING
Hazardous voltage . Solidly ground all equipment . Failure
to comply can result in death, severe personal injury,
and equipment damage .
T223 .2
WARNING
This equipment is not intended to protect human
life . Follow all locally approved procedures and safety
practices when installing or operating this equipment .
Failure to comply can result in death, severe personal
injury and equipment damage .

Control Wiring
Connections for control of the capacitor switch and auxiliary
functions are made through the receptacles located on the
the bottom of the junction box. There are two different
receptacles. The 12-pin receptacle is used for power and
functional operation, and the 10-pin receptacle is use for
switching auxiliary equipment.
Cable lengths and control boxes which house controller
modules, are optional. If supplied the control box will be
provided with wiring to junction box receptacles.
See additional details for control and auxiliary cables below;

Three-wire control
Remote control of the TriSync capacitor switch is supplied
by a single-pole, double-throw switch (three-wire control).
Any manual switch, relay contact, time switch, voltage-,
current- or photo-electric-controlled switch, or similar device
can be used, provided the control circuit is energized per
table 1 open and close cycle time (ms) this time is a little
different for 38kV. it is given in the ratings table for each
operation.
Eaton requires a 10-second cool-down period
between open and close operations to ensure the
switch coil does not overheat or become damaged .
