Infeed systems for 3RA6

SIRIUS Innovations Supplement 2011

■

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

maintenance work during the plant's operating phase.

The infeed system provides the possibility of completely

prewiring the main circuit without a compact starter needing to

be connected 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 conductor cross-section of max. 2/0 AWG on the

feeder terminal block.

The infeed system can be mounted on a standard mounting rail

or flat surfaces.
