Circuit Breaker Accessory

Overview

The General Electric Voltage Module is used to provide
+24Vdc Control Power to Spectra
Case Circuit Breakers with microEntelliGuard
MicroVersaTrip
Cable System. The Module also provides voltage­sensing signals to Spectra
Breakers with microEntelliGuard
PM Trip Units on the same UL Listed Circuit Breaker
Accessory Distribution Cable System. The Voltage
Module is rated 24 watts (+24Vdc @ 1.0 Amp) and
has the maximum capacity to power a Distribution
Cable System consisting of 20 Spectra

GEH-6250 Installation Instructions

The Voltage Module contains both a Power Supply
Plate and a Voltage Conditioner Assembly as integral
components. The module also includes fuse protection
for the AC source input terminals (see Figure 3). The
Voltage Module is available in seven ratings. Table 1
contains a listing of all GE Voltage Modules. All units are
rated 60 Hz.

EntelliGuard™ TU or a MicroVersaTrip® PM Trip Unit. (Do

®

not connect this voltage signal to a Spectra

Trip Unit.
The voltage signal structure is different between the
MCCB and ACB/ICCB Trip Unit platforms).

CAUTION: The voltage-sensing signal structure for

®

MicroVersaTrip

PM and EntelliGuard™ TU Trip Units
used in Air Circuit/Insulated Case Breakers is different
than the voltage-sensing signal structure used on

®

Spectra

RMS Breakers with MicroVersaTrip® PM or

microEntelliGuard™ Trip Units.

Additional 24Vdc output connections are supplied for
applications where +24Vdc control power is required
independent of the Distribution Cable System (i.e.
feeding Air Circuit Breakers and/or Insulated Case

®

Breakers with a MicroVersaTrip

PM/Plus Trip Units).

NOTE: THE VOLTAGE MODULE IS SIZED FOR A MAXIMUM
OF 20 BREAKERS. Use of the Voltage Module to provide
voltage-sensing signals and/or +24Vdc control power
to a main Air Circuit Breaker or a main Insulated Case

maximum cabling length of the system remains 40 feet.

A communications connection is provided for
applications where data is transmitted to an external
intelligent device (See Table 2). The distribution cable
system is used to interconnect the voltage signal on

®

the Voltage Conditioner Plate and the Spectra

RMS

Molded-Case Circuit Breakers.

CAUTION: The microEntelliGuard™ trip unit system
uses modbus communications and should never be
connected to a Commnet bus

An additional voltage output connection is available for
applications where a voltage signal is needed on an Air
Circuit Breaker or Insulated Case Circuit Breaker with an

Supplemental 24Vdc input terminals are provided
for systems that have access to an external +24Vdc
power supply. If this supplemental input is connected,
the Voltage Module will continue to pass the control
power to breakers and accessories connected to the
Distribution Cable System if the primary AC power is
lost or drops below the minimum requirement. This
backup input must meet ANSI C37.90.1 for oscillatory
and fast transient surges or damage to the Voltage
Module may result (the Voltage Module provides this
protection for the primary AC input). By plugging the
Voltage Module into the Distribution Cable System,
you create system wide signals that are available to

®

all Spectra

RMS Molded-Case Circuit Breakers with

or MicroVersaTrip® PM/Plus Trip
Units connected to the system; a list of available signals
appears in Table 2.

The Voltage Module contains eight connection points.
Refer to Figures 5A and 5B or 6A and 6B for connection
details and location information. The following is a
detailed list of the Voltage Module connection points:

• “To Distribution Cable” (2x)
– 12-pin plug connectors that mate with the 12-pin

receptacle of a Distribution Cable Harness (catalog
number SDCHA11, SDCHA30 or SDCHA60). If the

®

Voltage Module is factory installed in a Spectra
Series Switchboard these connections are factory
wired to Distribution Cable Junction Boxes (catalog
number SDCJBB).

• “Input”
– Three-screw terminal block on the Power Supply

assembly. Use the one-terminal “GND” screw for
connection of the ground. If the Voltage Module is

®

factory installed in a Spectra

Series Switchboard,
this connection is wired to the switchboard
equipment ground (the other two-terminal screws
are pre-wired to the load side of the Power Supply
Plate fuse block).

• “Communications”
– Two-screw terminal block for Modbus

communications link or for Commnet link to the GE
POWER LEADER™ Network.

• “Supplemental Input 24Vdc”
– Two-screw terminal block for connection to an

external +24Vdc power supply.

• “Output to ACB/ICCB”
– Three-screw terminal block for an additional voltage

®

sensing signal output to MicroVersaTrip

™

EntelliGuard

TU Trip Units in Air Circuit Breakers

PM or

and/or Insulated Case Breakers.

• “Output to 24Vdc”
– Two-screw terminal block for an additional control

®

power output to MicroVersaTrip

or EntelliGuard™
TU Trip Units in Air Circuit Breakers and/or Insulated
Case Breakers.

• Three-phase rear pressure connector
– Provides an AC source connection for control power

and voltage sensing signals. If the Voltage Module is

®

factory installed in a Spectra

Series Switchboard,
these connections mate with the vertical bus bars in
the switchboard. For catalog number ADSVMA120Y
and ADSVMA277Y, an additional AC neutral
connection must be made at one of the potential
transformers. This connection is factory wired if the

®

Voltage Module is factory installed in a Spectra
Series Switchboard.
