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 . 

G102 .1

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 .

 

A connection diagram for a standard three-wire control is 

shown in Figure 3.
