Configuration
The main conductors can be connected to the screw-type infeeds of the infeed system from
both the top and the bottom.
Therefore, the infeed system for 3RA6 is particularly suitable for multi-tier configuration.
Within this context, the bottom terminal openings of the top tier need to be connected to the
top terminal openings of the bottom tier using a conductor.
