Example:

To specify a VFI unit use the following

procedure:

1. Build the descriptor by completing the

fields based on the Switchgear

requirements:

For example, KPDE-VF9-32 is the

descriptor for the following standard unit:

•

Pad-Mounted, Double-Sided unit

•

E200 Fluid insulation

•

15 kV, 600 A deadbreak bushings on

source ways, 200 A loadbreak bush-

ing wells on tap ways

•

Model 9 - Two switched source ways

and Two vacuum fault interrupter

protected Tap ways

•

Mild-Steel construction

•

Side-hinged doors

•

Tri-phase control for the vacuum

fault interrupter tap ways (Tri-Phase

control with “EF” TCC curve is the

standard control that ships with the VFI

unit. If a different control is required,

select the appropriate control from

Table10 and the desired TCC curve

from Table11.)

•

Unit is of standard Bell Green/

Munsell 7GY paint. If custom color is

required, refer to Table12.

2. Identify the options or accessories for

inclusion with the standard unit. Refer

to Tables 7-21.

3. Submit the descriptor with a list of

options and accessories to your Eaton’s

Cooper Power Systems representative

for a quotation.

S for Single-Sided configuration

E Insulating Medium

O for Mineral Oil insulation

F for Envirotemp™ FR3™ fluid (consult factory)

E for E200 Fluid

S for SF

insulation

VF Type of unit

VF for VFI unit

RV for RVAC unit (model 13A & 10)

9 Model number of the unit

refer to column “model” in Table 4 for

double-sided unit or for single-sided unit.

3 Unit Phase type

3 for Three-Phase unit

1 for Single-Phase unit

2 Bushing Configuration

Digit represents ampere rating of bushing

and voltage rating of gear per Table 5,

below.

KP D E - VF 9- 3 2 is the required descriptor†

* Single-Phase units available. Consult Factory.

** For 900 A continuous rating. Consult Factory.

‡ For 16000 A interrupting rating. Consult Factory.

† The descriptor is not the catalog number, but a shorthand method of describing the unit.
