We offer you a unique portfolio for efficient energy management in the industry – a process that is used to optimize the energy requirements. We divide operational energy management into the three phases: identification, evaluation and implementation, and support you with suitable hardware and software solutions in each phase of the process.
The innovative SIRIUS industrial controls products can also make a major contribution to the energy efficiency of a plant. For more information, see http://www.siemens.com/sirius/energysaving.
With the 3RA6 compact feeders, control cabinets heat up less because power losses have been minimized by operation:
Lower intrinsic power loss (than comparable motor feeders with thermal overload trip) thanks to electronic current analysis
Lower power losses (than conventional load feeders) because there is only one switching point for short circuit and operational switching
Lower control circuit power losses (compared with conventional switching devices) as a result of electronic control of switching points
Thanks to the above advantages, additional energy savings are possible because less cooling is required (and a more compact design is possible)
Product advantages
The SIRIUS 3RA6 compact feeders offer a number of advantages, the most important being:
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 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 mm?
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.
