■

Overview (continued)

Available for the 3RA61 and 3RA64 direct-on-line starters is a

slot for an optional auxiliary switch block (optionally 2 NO, 2 NC

or 1 NO + 1 NC) and for the 3RA62 and 3RA65 reversing starters

there are

two slots (

for auxiliary switch blocks see "Accessories"

on Page 6/84).

Unlike the direct-on-line starter, the 3RA62 reversing starter has

one auxiliary contact (1 NO) per direction of rotation per main

contact.

Positively-driven operation of the auxiliary contacts

Positively-driven operation between individual auxiliary circuits

exists for the compact feeder in the version as a direct-on-line

starter for parallel wiring (3RA61) between the auxiliary circuits

of the NC contacts (NC 21-22) and the NO contacts (NO 13-14)

in the basic unit.

In addition the optional auxiliary switch block offers positively

driven contacts in the version 3RA69 13-1A, each with one NC

contact and one NO contact.

Benefits

The SIRIUS 3RA6 compact feeders offer a number of benefits:

• Compact design saves space in the control cabinet

• Little planning and assembly work and far less wiring thanks

to a single complete unit with one order number

• Little variance through 3 wide voltage ranges and 5 wide

setting ranges for the rated current mean low stock levels

• High plant availability through integrated functionalities such

as prevention of main contact welding and shut-down at end

of service life

• Greater productivity through automatic device reset in case of

overload and differentiated detection of overload and short-

circuit

• Easy checking of the wiring and testing of the motor direction

prior to start-up thanks to optional "control kits"

• Speedy replacement of devices thanks to removable termi-

nals with spring-type and screw connections in the main and

control circuit

• Efficient power distribution through the related SIRIUS infeed

system for 3RA6

• Direct connection of the motor feeder cable to the SIRIUS in-

feed system for 3RA6 thanks to integrated PE bar

• Connecting and looping through incoming feeders up to a

cross-section of 70 mm²

• When using the infeed system for 3RA6, possibility of directly

connecting the motor cable without intermediate terminals

• Integration in Totally Integrated Automation thanks to the

optional connection to AS-Interface or IO-Link

The SIRIUS 3RA6 compact feeders create the basis for high-

availability and future-proof machine concepts.
