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.

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 for
connecting to circuit breakers of other sizes and to the 3RV29 infeed system are also
presented within this context.
Furthermore, to facilitate configuration the manual contains dimension drawings and
technical data of the system components.

Security information
Siemens provides products and solutions with industrial security functions that support the
secure operation of plants, systems, machines, and networks.
In order to protect plants, systems, machines and networks against cyber threats, it is
necessary to implement – and continuously maintain – a holistic, state-of-the-art industrial
security concept. Siemens’ products and solutions only form one element of such a concept.
Customer is responsible to prevent unauthorized access to its plants, systems, machines
and networks. Systems, machines and components should only be connected to the
enterprise network or the internet if and to the extent necessary and with appropriate security
measures (e.g. use of firewalls and network segmentation) in place.
Additionally, Siemens’ guidance on appropriate security measures should be taken into
account. You can find more information about industrial security by visiting:

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.
The 3RA64/3RA65 compact starter with IO-Link can communicate via IO-Link.
