Warning notice system
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury
will
result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury
may
result if proper precautions are not taken.
CAUTION
indicates that minor personal injury can result if proper precautions are not taken.
NOTICE
indicates that property damage can result if proper precautions are not taken.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.
Qualified Personnel
The product/system described in this documentation may be operated only by
personnel qualified
for the specific
task in accordance with the relevant documentation, in particular its warning notices and safety instructions.

Introduction
1
Purpose of this manual
This SIRIUS 3RA6 Compact Starter Manual describes the compact starter and its functions.
It contains information about configuration, commissioning and servicing.
As well as providing information about the compact starter itself, the manual also deals with
compatible infeed systems. These are the SIRIUS infeed system for 3RA6, the
insulated 3RV19 three-phase busbar system and the 8US busbar adapter. The options in
terms of connecting to circuit breakers of other sizes and to the 3RV19/3RV29 infeed system
are also discussed within this context.
Furthermore, to facilitate configuration the manual contains dimension drawings and
technical data of the system components.

3.1
System overview
Features
The SIRIUS compact starter is a universal, weld-free motor feeder in accordance with
IEC/EN 60947-6-2. It combines the functions of a circuit breaker, a solid-state overload relay
and a contactor within a single enclosure and can be used in any application involving the
direct starting of standard three-phase motors with a rating of up to 32 A
(approx. 15 kW/400 V).
The compact starter is available as either a direct or a reversing starter.
As an option, an AS-i mounting module can be mounted on the 3RA61/3RA62 compact
starter with a 24 V control supply voltage. The AS-i mounting module enables the compact
starter to communicate via an AS-Interface.

Infeed system for 3RA6 The infeed system for 3RA6 is a
modular infeed system with an
optional PE system. The permanent
wiring means that compact starters
can be mounted quickly and easily.
