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.
