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
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).
NOTE: THE VOLTAGE CONDITIONER ASSEMBLY IS SIZED
FOR A MAXIMUM OF 20 BREAKERS. Use of the Voltage
Conditioner Plate to provide voltage sensing signals
and/or +24Vdc control power to a main Air Circuit
Breaker or a main Insulated Case Breaker with a
MicroVersaTrip
® PM/Plus or EntelliGuard TM TU Trip Unit
reduces the total quantity of 20 Spectra ® RMS Molded-
Case Circuit Breakers with microEntelliGuard TM or
MicroVersaTrip ® PM/Plus Trip Units by one. The overall
maximum cabling length of the system remains 40 feet.
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
informtaion / metering at Spectra
® RMS Molded-
Case Circuit Breakers with MicroVersaTrip ® PM Trip
Units and/or MicroVersaTrip ® PM Programmers in Air
Circuit Breakers or Insulated Case Circuit Breakers.
• “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”
– Two-screw terminal block for connection to
communications network.
• “Output to ACB/ICCB”
– Three-screw terminal block for optional voltage-
sensing signal output to MicroVersaTrip ® PM or
EntelliGuard™ TU Trip Units in Air Circuit Breakers
and/or Insulated Case Circuit Breakers.
The distribution cable system is used to interconnect
the voltage signal on the Voltage Conditioner Plate and
the Spectra
® RMS Molded-Case Circuit Breakers.
