Overview
Accessories for SIRIUS 3RA6 compact starters
The following accessories are available specially for the
3RA6 compact starters:
•
Infeed system for 3RA6:
see page 8/79 onwards
•
AS-i add-on modules:
see page 8/77 onwards
"AS-Interface add-on modules"
•
External auxiliary switch blocks: Snap-on auxiliary switch as
versions 2 NO, 2 NC and 1 NO + 1 NC with screw or spring-
type terminals; the contacts of the auxiliary switch block open
and close jointly with the main contacts of the compact starter.
The NC contacts are designed as mirror contacts.
•
Control kit: Aid for manually closing the main contacts to
check the wiring and motor direction under conditions of
short-circuit protection
•
Adapter for screw fixing the compact starter,
including push-in lugs
•
Main circuit terminal: Available with screw and spring-type
terminals
•
Main circuit terminal for mixed connection methods:
Using the main circuit terminal for mixed connection methods
it is also possible to switch from screw connection on the input
side to spring-type connection on the outgoing side in the
main circuit.
This means for example that several compact starters can be
mounted side by side and be cost-efficiently connected using
the three-phase busbars on the infeed side. The motors are
then connected directly by the quick and reliably contacting
spring-type connection method.
Accessories for UL applications
The terminal block for "Self-Protected Combination Motor
Controller", type E is available for complying with the clearance
and creepage distances demanded according to UL 508.
Accessories for infeed using three-phase busbar systems
The three-phase busbars can be used as an easy, time-saving
and clearly arranged means of feeding SIRIUS 3RA6 compact
starters with screw connection. Motor starter protector sizes S00
and S0 can also be integrated.
The busbars are suitable for between two and five devices.
However, any kind of extension up to a maximum summation
current of 63 A is possible by clamping the tags of an additional
busbar (rotated by 180°) underneath the terminals of the respec-
tive last motor starter protector.
Motor starter protectors S00 and S0 of the 3RV2 series can be
combined in any way (without a special connecting piece).
The motor starter protectors are supplied by appropriate infeed
terminals. Special infeed terminals are required for constructing
"Type E Starters" according to UL/CSA.
The three-phase busbar systems are finger-safe but empty
connection tags must be fitted with covers. They are designed
for any short-circuit stress which can occur at the output side
of connected SIRIUS 3RA6 compact starters or motor starter
protectors.
Busbar adapters for 60 mm systems
The compact starters are mounted directly with the aid of busbar
adapters on busbar systems with 60 mm center-to-center
clearance in order to save space and to reduce infeed times
and costs. These feeders are suitable for copper busbars with a
width from 12 to 30 mm. The busbars can be 4 to 5 mm or 10 mm
thick.
The 8US busbar system can be loaded with a maximum
summation current of 630 A.
The "reversing starter" version requires a device holder along
side the busbar adapter for lateral mounting.
The compact starters are snapped onto the adapter and
connected on the line side. This prepared unit is then plugged
directly onto the busbar system, and is thus connected both
mechanically and electrically at the same time.
For more accessories such as incoming and outgoing terminals,
flat copper profiles etc.,

Accessories for operation with closed control cabinet doors
Door-coupling rotary operating mechanisms for standard and
emergency-stop applications are available for operating the
compact starter with closed control cabinet doors.
Accessories for SIRIUS 3RA6 compact starters in
IO-Link version
The following accessories are available specially for the 3RA64,
3RA65 compact starters:
•
The 4SI SIRIUS electronic module as IO-Link master allows for
the simple and economical connection of SIRIUS controls with
IO-Link (e. g. up to four groups of 4 compact starters) to the
multifunctional SIMATIC ET 200S distributed I/O system.
•
Additional connection cables for side-by-side mounting of up
to four compact starters
•
Operator panel for on-site control and diagnostics of up to four
compact starters coupled to each other
