Circuit Breaker Accessory
Overview
The General Electric Distribution Cable Harness is a
modular connector used to carry a variety of electronic
signals between Spectra
Breakers with microEntelliGuard
PM/Plus Trip Units and Distribution Cable Accessories.
The Distribution Cable accessories supported by the
Distribution Cable Harness are as follows:
• Power Supply Plate
• Voltage Conditioner Plate
• Power Supply Assembly
• Voltage Conditioner Assembly
• Distribution Cable Junction Box
• Distribution Cable Extension
• Distribution Cable Terminal Block
• Voltage Module
®
RMS Molded-Case Circuit
TM
or MicroVersaTrip®
The Distribution Cable Harness is also used in GE
Spectra
Distribution Cable Junction Boxes (Cat. Nos. SDCJBB
and SDCJBBC) to other Distribution Cable Junction
Boxes or to connect Distribution Cable Boxes to the
Voltage Module.
Because both ends are receptacles, you cannot use the
Distribution Cable Harness as an extension cable; use
the Distribution Cable Extension (Cat. Nos. SDCEA30
and SDCEA30C) for this application (microEntelliGuard
Trip Units with 20-pin connectors use the SDCEA30C
extension cable).

Figure 1 shows how the Distribution Cable Harness is used in a typical MicroVersaTrip® PM system. Figure 2 shows
how the Distribution Cable Harness is used in a typical MicroVersaTrip
®
Plus system. The microEntelliGuard
TM
Trip
Unit can be used with either configuration, i.e. Figure 1 or Figure 2. The connection diagram shown in Figure 2
TM
applies to microEntelliGuard
Trip Units with Basic Metering.

The electronic signals supported by the Distribution
Cable Harness vary depending on the type of trip unit
used; a list of supported functions is as follows:

another Distribution Cable Accessory, align the harness
receptacle interlock with the plug hook of the mating
Distribution Cable accessory and insert the receptacle
into the plug until the interlock and hook overlap and
catch (see Figure 4).
To disconnect the Distribution Cable Harness, press
down at the rear of the receptacle interlock until the
interlock clears the hook, and remove the receptacle
(see Figure 5).
Figure 3 shows the connector pinout for the Distribution
Cable Harness for each type of trip unit.
Connections
The Distribution Cable Harness contains a 12-pin
receptacle connector on each end. The connectors are
keyed so they cannot be inserted incorrectly into a
mating 12-pin plug connector.
