GE Industrial Solutions SDCJBB - Manual

Overview
The General Electric Distribution Cable Junction Box
is a modular connector used to provide quick, easy
and reliable attachment of Spectra
® RMS Molded-
Case Circuit Breakers with microEntelliGuard TM ,
MicroVersaTrip ® PM or Plus Trip Units to the Distribution
Cable System. The electronic signals supported by the
Distribution Cable Junction Box vary depending on
the type of Molded-Case Circuit Breaker used; a list of
supported functions appears below.
Input signals to Spectra ® RMS Breaker with
MicroVersaTrip ® PM Trip Unit
• control power (+24vdc)
• control power (common)
• system communications (Comm +)
• system communications (Comm –)
• breaker position (via installed aux. switch - red wire)
• breaker position (via installed aux. switch - white wire)
• voltage A f (must be from Voltage Module or Voltage
Conditioner Plate or Voltage Conditioner Assembly)
• voltage B f (must be from Voltage Module or Voltage
