Load feeders & motor starters
Sirius Compact Starter 3RA6
Compact Design that saves space in the control cabinet.
Features & Benefits
- Little planning and assembly work and far less wiring thanks to a single complete unit with one article number
- Low variance and therefore low stock levels, with two wide voltage ranges and five wide setting ranges for the rated current
- High plant availability through integrated functionalities such as prevention of main contact welding and disconnection at end of service life
- Enhanced 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 terminals with spring-loaded 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 infeed 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

SIRIUS 3RA2 load feeders
Minimum planning and assembly work and far less wiring with the preassembled complete units.
Features & Benefits
- Plug-in connectors from the motor starter protector to all types of SIRIUS controls, for quicker and error-free assembly of feeders with screw and spring-type terminals
- High planning reliability through consistent combination tests for fuseless and fused configurations according to IEX and UL/CSA
- Comprehensive approvals for use worldwide on request, see www.siemens.com/industrial-controls/support
- High operational reliability through short-circuit breaking capacity of 150 kA with type of coordination “1” and “2”
- Uniform accessories for sizes S00, S0, S2 and S3
- Spring-type terminals possible throughout: Enhanced operational reliability (vibration-resistant wiring) and less wiring work thanks to plug-in connections (S00 and S0 only)
- Power loss 5 to 10% smaller than for comparable devices, hence lower energy consumption
- Connection of feeders to the control system through standardized system connection (IO‑Link and AS‑i), for fast integration in TIA and less wiring work
