More space in the control cabinet

21.04.2008
With the Sirius 3RA6 compact starter, Siemens Industry Automation (IA) has added to its portfolio a new low-voltage switchgear product for three-phase AC standard motors up to 32 amps.

The functions of overload relay, circuit breaker, and contactor are bundled in the device. This reduces installation and wiring overhead for the user and creates more space in the control cabinet. The new compact starter has its own infeed system for power supply as well as a mounting module for simple connection to AS-Interface.


At the same time, the variance of the load feeders has been significantly reduced with the Sirius 3RA6 starter. With five wide setting ranges up to 32 amps rated current, as well as three wide voltage ranges for AC/DC current with 24, 42 to 70 and 110 to 240 volts, the devices, available as direct starters or reversing starters, cover a large percentage of the application range.

With the associated Control Kit, the user performs an early check on the wiring and motor direction even before the plant starts up. This can prevent faults and increase plant availability, as can safe shutdown at the end of service life, separate indication of overload and short-circuit, and auto reset following overload trip. Removable spring-loaded and screw-type terminals also simplify device replacement for service purposes.
For efficient energy supply to the main circuit, the user can simply plug the Sirius 3RA6 compact starter into the associated, pre-wired infeed system and thus significantly reduce the wiring overhead. This infeed system can be flexibly expanded to suit the plant by adding additional slots and Sirius industrial controls components such as 3RV1 circuit breakers or the 3RV19 infeed system. As an option PE terminals are also available for this system. This provides the possibility of directly connecting the motor cables to the Sirius infeed system for 3RA6.

To further reduce the overhead involved in integration into the control circuit, Siemens offers additional, corresponding AS-i mounting modules with which the Sirius 3RA6 compact starter can be connected directly to the AS-Interface. The mounting module can easily be connected to the compact starter and used as an A/B slave for the AS-Interface. All the diagnostics and status data of the compact starter are thus forwarded direct to the higher-level controller.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
