Advantages through energy efficiency

Overview of the energy management process

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.
