SIRIUS modular system
Simple, efficient and always up-to-date
Size S3
Building control cabinets should be fast, simple, flexible and
space-saving.
The unique SIRIUS modular system offers everything you
need for switching, protecting and starting motors and
industrial systems. It is a modular selection of standard
components which are optimally coordinated, can be
combined with ease and use the same accessories to a large
extent.
With its wide range of components, the SIRIUS modular
system features the most diverse functions for use in the
control cabinet, and offers a host of benefits in assembly
and handling, in application monitoring, and also in
controller interfacing, or when planning and configuring.
Thanks to the latest innovations to the modular system in
sizes S00, S0, S2 and S3 up to 100 A/115 A, today's SIRIUS
modular system shows even more functional diversity and
first-time highlights.
HIGHLIGHTS
•
Feeder assemblies that can be plugged in completely
without tools thanks to the consistent use of
spring-type connections in sizes S00 and S0
•
Two- and three-phase 3RR2 monitoring relays for
current monitoring for direct mounting onto contactors
•
3RA27 and 3RA28 function modules feature snap-on
connection to contactors enabling the easiest possible
assembly of direct-on-line starters, reversing starters,
and wye-delta starters and connection to the controller
using less wiring via AS-Interface or IO-Link
•
3RB24 overload relay with communication capability,
current value transmission, and control of the
contactors via IO-Link
•
One highlight of the SIRIUS devices is their IE3/IE4
suitability, so that they are optimally equipped for
conversion to the new IE3/IE4 generation of motors
