1.3 System features
The entire SIRIUS range of devices is divided up into only four frame sizes
(S00 up to 5.5 kW, S0 up to 11 kW, S2 up to 22 kW, and S3 up to 45 kW)
with three different widths (45 mm for S00 and S0, 55 mm for S2, and
70 mm for S3) and has a uniform range of accessories for all frame sizes.
Modular system
The individual components of the SIRIUS range are building blocks in a mod-
ular system that are harmonized in terms of both their frame size and their
technical specifications. This ensures that individual requirements can be
met quickly and cost-effectively.
Uniformity
The devices are harmonized with regard to their ratings and their technical
specifications:
• The same width ensures rapid installation.
• The terminal systems are standardized, and devices with the same rated
current have the same terminals.
Performance capability
All SIRIUS devices can be mounted side by side without derating in an ambi-
ent air temperature of up to 60 °C.
Accessories
All accessories, such as the auxiliary switches and surge suppressors, can
be mounted and removed without tools.
You can use link modules that connect devices both mechanically and elec-
trically to put together combinations of devices and build fuseless load feed-
ers.
Communication
Direct communication with a higher-level controller is possible using:
• The AS-Interface load feeder module
• The ET 200X distributed I/O devices on the PROFIBUS-DP bus system
• The ET 200S system
