Overview
The General Electric Voltage Conditioner Plate is used
to provide voltage-sensing signals to Spectra
Molded-Case Circuit Breakers with microEntelliGuard
or MicroVersaTrip
Cable System. The Voltage Conditioner Plate includes
the Voltage Conditioner Assembly (catalog number
SVCAA) as an integral component and also includes fuse
protection for the AC source input terminals and three
1-VA @ 60 Hz high accuracy potential transformers. The
plate has the maximum capacity to provide voltagesensing signals to a Distribution Cable System consisting
of 20 Spectra
microEntelliGuard
with a maximum system cable length of 40 feet.

The Voltage Conditioner Plate requires a power supply
source of +24Vdc to operate properly. The Power
Supply Assembly (catalog number SPSAA) or Power
Supply Plate (catalog number SPSA120, SPSA208,
SPSA240, SPSA480 or SPSA600) can provide this
required input. The unit also requires direct AC voltage
inputs from the AC source (ratings of 120Vac, 208Vac,
240Vac, 277Vac, 480Vac or 600Vac are available). The
Voltage Conditioner Plate is designed to operate in
temperatures between 0°C and 70°C.

not connect this voltage signal to a Spectra

The Voltage Conditioner Plate contains five connection
points. The following list contains a description and
type of connection points.
• “To Distribution Cable”
– 12-pin plug connector that mates with the 12-pin
receptacle of a Distribution Cable Harness (catalog
number SDCHA11, SDCHA30 or SDCHA60).
• “To Power Supply”
– 12-pin plug connector that mates with the 12-
pin receptacle of the Distribution Cable Harness
(catalog number SDCHA11, SDCHA30 or SDCHA60).
The other end of the harness MUST mate to either
a Power Supply Assembly (catalog number SPSAA)
or a Power Supply Plate (catalog number SPSA120,
SPSA208, SPSA240, SPSA480 OR SPSA600). Failure to
do so will result in the absence of a voltage-sensing
signal and inaccuracies in voltage dependent

• “Input Voltage”
– Three-screw terminals on the fuse block for
connection of the primaray AC source. For Power
Supply Plates (Catalog Numbers SPSA120 and
SPSA277), an additional AC neutral connection must
be made at one of the potential transformers.
• “Communications”

GEH-6252 Installation Instructions
By plugging the Voltage Conditioner Plate into the
Distribution Cable System you create system wide
signals that are available to all breakers connected to
the system; a list of those functions appears in Table 3.

Connections
The screw terminals on the Voltage Conditioner Plate
are labeled by function for clarity. The terminal strip
pockets on the AC INPUT fuse block will accommodate
a spade lug or ring terminal with a tongue width up
to 0.45 inches. The terminal screw size is 10-32. The
terminal strip pockets on the Voltage Conditioner
Assembly will accommodate a spade lug or ring terminal
with a tongue width up to 0.320 inches. The terminal
screw size is 10-32. To make the connection, attach an
appropriate spade lug or ring terminal to the wire, then
slip the fastener beneath the terminal screw and tighten.
The Voltage Conditioner Plate also contains two 12pin plug connectors. The connectors are keyed so
they cannot be inserted incorrectly into a mating 12pin receptacle connector. To connect to the Voltage
Conditioner Plate plug(s), align the receptacle interlock
connector of a Distribution Cable Harness with the plug
hook connector of the Voltage Conditioner Plate. Insert
the receptacle until the interlock and hook catch (see
Figure 5). To disconnect from the Voltage Conditioner
Plate, press down at the rear of the receptacle interlock
until the interlock clears the plug hook, and withdraw
the receptacle interlock (see Figure 6).
PARTS AND OPTIONS
The only user-serviceable components or parts on the
Voltage Conditioner Plate are the fuses in the AC INPUT
fuse block. The fuses listed in Table 4 are recommended
as replacements for use with the Voltage Conditioner
Plate. Failure to use the proper type of fuses can result
in damage to the accessory. Three fuses per Voltage
Conditioner Plate are required.
If you prefer to purchase a voltage-sensing source
without the factory mounted AC line fuses and high
accuracy potential transformers, a Voltage Conditioner
Assembly is available. This assembly still requires AC
line fuse protection and the high accuracy potential
transformers to work properly. Table 5 lists the details
on the GE Voltage Conditioner Assembly.
