1.1 Introduction
1.1.1 Modular system for SIRIUS
System is everything: The SIRIUS modular system for the control cabinet
Siemens is one of the most important manufacturers of switching devices, whose product
range extends from devices that switch just a few milliamps to motor starter protectors for
power distribution. The process of configuring control cabinets must be quick, easy, flexible,
and must enable you to create space-saving solutions.
This is exactly what Siemens offers with its unique SIRIUS modular system. This system
offers all the functions and devices you will need for switching, starting, protecting, and
monitoring motors and systems. In other words, it provides a modular range of standard
components, which are perfectly matched to one another, can be combined really easily, and
use the same accessories. That's how easy controls and distribution can be.
Continuous further development and constant innovations ensure that, with SIRIUS, you are
ideally equipped to meet the challenges of today and tomorrow, and can benefit from cost-
effective solutions. All the components that make up the SIRIUS modular system are
characterized by a space-saving design and a high degree of flexibility. Configuration,
installation, wiring, and maintenance work are all extremely quick and easy to perform.
In further developing these products, a great deal of emphasis has consistently been placed
on meeting or even exceeding requirements in terms of essential performance features,
electrical and mechanical durability, dimensions, and ease of mounting and maintenance.
Environmentally-friendly and recyclable materials have been developed and used in the
system to reflect the ecological awareness that has grown at a quite incredible rate over the
last decade in particular. In the field of low-voltage switching devices, this has resulted in the
creation of modern industrial switching devices which fulfill all requirements with regard to
environmental compatibility.
Building on decades of experience, a totally new generation of devices for performing
switching, starting, protecting, and monitoring functions was created for the large and ever
growing number of motorized operating mechanism in the range up to 18.5 kW: SIRIUS
Innovations.
These new SIRIUS devices meet all requirements that have arisen in the field and can be
used as individual devices, as modules for complete load feeders, or installed in low-voltage
distribution boards or low-voltage switchgear. So no matter whether you want to configure
load feeders with motor starter protectors or overload relays, contactors, or soft starters,
SIRIUS has just the product you will need for any application.
