Overview
The infeed system for 3RA6 compact starters enables far less
wiring in the main circuit and, thanks to the easy exchangeability
of the compact starters, reduces the usual downtimes for main-
tenance work during the plant's operating phase.
The infeed system provides the possibility of completely prewir-
ing the main circuit without a compact starter needing to be con-
nected at the same time. As the result of the removable terminals
in the main circuit, compact starters can be integrated in an
infeed system in an easy manner (without the use of tools).
In addition, the integrated PE bar means it is optionally possible
to connect the motor cable directly to the infeed system without
additional intermediate terminals. The infeed system for 3RA6
compact starters is designed for summation currents up to
100 A with a maximum 70 mm² conductor cross-section on the
feeder terminal block.
The infeed system can be mounted on a standard mounting rail
or flat surfaces.
