Monitoring in just a few short steps
More and more often, drives are being required to monitor complex processes or expensive
machines to ensure they are functioning correctly. Previous solutions to such tasks involved
quite a lot of wiring. That's why the current monitoring relay has been fully integrated in the
main circuit in the new SIRIUS modular system. Designed like an overload relay, apparent or
active current measuring can thus be added in just a few short steps; but phase sequence,
phase failure, and other process-relevant data can also be evaluated too.
Reduced wiring
The infeed and power distribution options for a group of feeders has also been optimized in
order to reduce the wiring in the main circuit. The SIRIUS 3RV29 infeed system now
benefits, for example, from having a spring-loaded connection system available throughout,
which means that whole groups of feeders can be assembled quickly and without the need
for tools.
Minimized planning and configuration outlay
In order to reduce the effort involved in planning and configuration to a minimum, Siemens
offers a range of Internet tools in addition to the standard documents in paper format. These
tools can help you to select the most suitable product for your needs, to find the associated
technical data quickly, and to put together the relevant technical documentation easily.
With its SIRIUS modular system switching devices in sizes S00 and S0, which have been
completely redeveloped, Siemens can meet all requirements up to 32/40 A. This equates to
over 80% of all typical applications.
Problem-free usage
With its versatile product range, the SIRIUS modular system offers technology which is
suitable for use in all industries and all regions of the world. The products have been tested
in accordance with common standards and have obtained the approvals required to ensure
that they can be used anywhere in the world without any problems.
Flexible mounting options
The devices have been designed for installation on standard mounting rails ("DIN rails"), as
well as for screw fixing. A whole range of link modules is available for easily connecting
switching devices, both electrically and mechanically. These link modules are used to
combine the individual components of the SIRIUS modular system together to create load
feeders. If you make use of the spring-loaded connection system, this can even be done
without the need for tools by simply plugging the different components together.
The spring-loaded connection system has now been extended to cover the entire product
range of sizes S00 and S0 for the main circuit and the control circuit. The ring cable lug
connection system is also available for use with particular applications and on request for
certain regions.
