Benefits

The SIRIUS 3RA6 compact starters offer a number of

advantages:

• Compact design saves space in the control cabinet

• Reduced planning and assembly work and far less wiring

thanks to a single complete unit with one order number

• Decreased variance thanks to 3 wide voltage ranges and

5 wide setting ranges for the rated current means stock levels

are kept to a minimum

• High plant availability due to integrated functionalities such as

prevention of main contact welding and safe disconnection at

end of service life

• Greater productivity provided by 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 the optional control kit device

• Rapid replacement of devices thanks to removable terminals

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

trol circuit

• Efficient power distribution via the related SIRIUS infeed sys-

tem for 3RA6

• Direct connection of the motor starter cable to the SIRIUS

infeed system for 3RA6 thanks to integrated PE bar

• Connecting and looping through multiple infeed systems up to

a cross-section of 2/0 AWG

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

connecting the motor wiring without intermediate terminals

• Integration in Totally Integrated Automation thanks to the

optional connection to AS-Interface or IO-Link

• Offers up to 80% energy savings when compared to conven-

tional starters

The SIRIUS 3RA6 compact starters create the basis for

high-availability and future-proof machine concepts.
