1.5.5 Flexible assembly methods
The SIRIUS modular system offers maximum flexibility in terms of configuration. The system
components can be assembled as feeders or mounted separately.
Table 1- 6 Assembly (mounted separately or assembled as feeders)
Separately mounted Mounted as complete feeders
The system components are assembled
separately (e.g. on separate DIN rails).
The system components are assembled as a unit
(e.g. with a link module).
The SIRIUS modular system offers the right solution for every type of assembly:
Table 1- 7 Assembly types
Assembly type Benefit
Feeders assembled from individual SIRIUS
devices
More than 40,000 tested combinations offer
solutions for almost every application.
SIRIUS 3RA2 load feeders More than 500 pre-assembled combinations
facilitate rapid and fault-free control cabinet
assembly.
SIRIUS 3RA6 compact starters Compact devices with high integrated functionality
for improved efficiency and reliability in the control
cabinet.
1.5.6 Performance capability
All innovations in the SIRIUS modular system can be mounted side by side and operated at
an ambient operating temperature of -25 °C to +60 °C. The SIRIUS modular system is
optimally suited for applications in demanding environments (in terms of dust exposure,
vibration and shock load; ATEX, etc.). All standard approvals have been obtained, making
the system suitable for use all over the world. In 400 V systems, size S00 covers a
performance range of up to 7.5 kW and size S0 up to 18.5 kW, with a width of just 45 mm. A
short-circuit breaking capacity of up to 150 kA is available.
