SIRIUS Infeed System.
Convincing advantages of screw and spring-loaded terminals
sirius
Flexible and in line with every requirement:
SIRIUS Infeed System
Whether screw or spring-loaded terminals, whether circuit-breaker,
load feeder or other components: Our SIRIUS infeed system acts as a
real all-rounder. Groups of several circuit-breakers (motor starter
protectors) – or complete load feeders – can be simply combined and
integrated. When it comes to spring-loaded terminals, our modular
SIRIUS system includes products, size S00 up to 5.5 kW at 400 V AC. If
you prefer controls with classic screw terminals, then circuit-breakers
and contactors, sizes S00 and S0 can be used. The SIRIUS infeed
system can be used for all motor feeders up to 11 kW. Relays,
miniature circuit-breakers or other components can be integrated.
This forms the optimum basis for a unified and user-friendly power
infeed and distribution system.

3-phase busbars with infeed
A 3-phase busbar with infeed is required to
connect the power. This comprises an infeed
module including two slots for each circuitbreaker as well as an end cover. Depending
on the version, the power is either fed in
from the left or right through spring-loaded
terminals. The spring-loaded terminals allow
cables to be connected using conductors
2
with cross-sections of up to 25 mm
equipped with connector sleeves.

3-phase busbars extend the
system
The 3-phase busbars to extend the system
comprise modules with either two or three
slots. The system can be extended as required
up to a current carrying capacity of 80 A.
An extension plug is supplied with each
module.
3a
Expansion connector
The 3RV19 17-5BA00 extension plug is used
to electrically connect adjacent 3-phase
busbars. This means that current carrying
capacities of up to 63 A are covered. An
extension plug is included with every 3-phase
busbar. This means that additional extension
plugs are only required as spare parts.
3b
Wider extension plug
Just like the conventional solution, the wider
3RV19 17-5E extension plug also reliably
establishes the electrical connection between
two 3-phase busbars. The electrical
characteristics, for instance, the maximum
current rating of 63 A, are identical. What's
the difference? When using the wider
extension plug, a clearance of 10 mm remains
between the connected busbars – thus
creating a wiring duct. This can be used to
route the control wiring.

feeders using spring-loaded
terminals, size S00:

The connections to the circuit-breaker and
contactor can therefore be made from below
so that a cable duct above the system is not
necessary.
4
End cover
The end cover is used to cover the 3-phase
busbars at the open end of the system. This
prevents voltage arcing to the control cabinet
and this is the reason that only one end cover
is required for each system. Every 3-phase
busbar with infeed includes an suitable end
cover so that additional end covers are only
required as spare part.
5
Connecting plug
The connecting plug is used to establish the
electrical connection between the 3-phase
busbars and the circuit-breaker. There are
three versions available:
• For 3RV circuit-breakers, size S00,
screw terminals, 3RV19 17-5CA00
• For 3RV circuit-breakers, size S0,
screw terminals, 3RV19 17-5AA00
• For 3RV circuit-breakers, size S00,
spring-loaded terminals, 3RV19 17-5AA00
6
Contactor socket
Load feeders can be reliably configured in
this system using contactor sockets. They are
suitable for contactors size S00 with springloaded terminals and are simply plugged
onto the 3-phase busbars. Direct and
reversing starters can be configured. Just
one contactor socket is required for direct
starters and two contactor sockets for
reversing starters. The systems can be flexibly
arranged when configuring reversing feeders:
either below one another (width: 45 mm) or
next to one another (width: 90 mm); whereby
in this case it is only possible to mechanically
interlock the contactors.
Generally, the infeed system is designed for
mounting on a 35 mm mounting rail with a
depth of 7.5 mm. The mounting rails
guarantee the required stability. When using
mounting rails with a depth of 15 mm, then
the distance piece located on the contactor
socket should be removed and located on
the mating piece. The distance piece can be
removed when using mounting rails with a
depth of 7.5 mm.
Compensating the depth
at the contactor socket
As an alternative to using a contactor socket,
for direct load feeders, size S00 with springloaded terminals, link modules can be used
to establish the connection between the
circuit-breaker and contactor. These types of
combined load feeders can then be directly
snapped onto the slots of the 3-phase
busbars. Feeders, sizes S00 and S0, are
generally implemented with these link
modules.
7
Terminal blocks and mounting
rails
Using the terminal block, not only can SIRIUS
circuit-breakers be integrated but also 1-, 2or 3-pole components. For instance a SIRIUS
relay or miniature circuit-breaker. In this case,
the terminal block is located in the slot of
the extension plug or in the end cover. This
means that an outlet can be provided in the
center or at the end of the infeed system.
The terminal block can be rotated through
180° and can then be interlocked with the
appropriate carrier module.
Terminal block
We also provide a 45 mm mounting rail to
simply integrate all 1-, 2- or 3-phase
components in the infeed system. This
mounting rail is simply screwed onto the
carrier module.

Versions with terminal block
The terminal block is located at the end of the
system. The cover is required in order to avoid
arcing.
The terminal block is integrated in the slot for
the extension plug in the middle of the system.
The cover cap has been removed, the busbars
are jumpered using the lyre-shaped contacts
of the terminal block.
Wiring duct between the modules.
Using the wider extension plug, a cable duct
of 10 mm can be formed between the
modules.
The circuit-breakers and contactors can be
connected from below so that a cable duct
above the system is not necessary.

New degree of flexibility when configuring and
System-orientated and modular:
the features
extending the system
•
Integration of motor feeders with screw and springloaded terminals possible
•
Maximum current rating of 63 A
•
Additional 1-, 2- or 3-pole components can be
additionally integrated using the terminal block
•
Either infeed from the left or right up to conductor
2
cross-sections of 25 mm
•
Mounting time savings by using simple plug-in connections
•
More free space in the control cabinet as a result of the
extremely compact design
•
High vibration strength, especially for controls with
spring-loaded terminals
•
Optional wiring duct between feeders
A basis module forms the foundation of the system. This
includes a 3-phase busbar with the appropriate infeed.
Depending on the version, the infeed with spring-loaded
terminal is mounted either at the left or right. This means
2
that a conductor cross-section of 25 mm can be used to
connect power to the system. The basis module always has
two slots to integrate a circuit-breaker. A connector is used
to establish the electrical connection between the 3-phase
busbars and the circuit-breakers. Extension modules in the
form of 3-phase busbars are available to expand the system.
The individual modules are connected to one another
through an extension plug.
The complete system can be snapped onto 35 mm mounting
rails according to DIN EN 50022 and can be expanded as
required up to a maximum current rating of 63 A. It is
especially easy to configure the system and without any
additional costs thanks to the straightforward plug-in
mounting system. The lateral system infeed reduces the
amount of space in the cabinet. The additional height of
the infeed system is then only 30 mm. The fact that it is
possible to feed-in power at both sides means the highest
degree of flexibility when engineering the system. Whether
an infeed at the left and outfeed to the right, whether a
ring infeed or if additional loads are to be supplied: You
have unlimited possibilities. And last but not least, the
terminal block and the wide extension plug allow additional
design versions.
