Cubicle busbars for Rectifier Modules
Introduction
The cubicle busbar assembly provides a simple way to interface to the rectifier modules, it’s an assembly of
either three or six connection busbars (type dependant). The busbars are assembled together and supported
by a clamp attached to the DELTA cross rails, this assists in supporting any attached cables.
Features
•
Busbar assembly allows the rectifier modules to be withdrawn or inserted without removing the
power cables through removal of the busbar connection bolts.
•
Connection points are more accessible through being moved to below the rectifier module and
its cross rails.
•
The clamp on the a.c. phase busbars supports any cables attached to the busbars. This support is
necessary for the rectifier modules designed for cable or busbar connection.
Variations
Three versions of the busbars are available which are suitable for the GDR721, GDR872 and GDR1168.

Interface
The a.c. busbar assembly connects directly behind the rectifier terminals and is supported from the DELTA
mounting framework.
External requirements
The a.c. busbars attach to the right of the rectifier module, their position dictated by the terminal positions.
Ensure there is sufficient creepage and clearance distances between any equipment mounted to the right of
the rectifier and the busbar assembly.
