3.1 System overview
General
The SIRIUS 3RA6 compact starter is a universal motor feeder that meets the requirements
of IEC / EN 60947-6-2 (weld-free). It combines the functions of a circuit breaker, a solid-state
overload relay and a contactor within a single housing and can be used in any application
involving the direct starting of standard induction 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 compact starter with a 24 V
control voltage. The AS-i mounting module enables the compact starter to communicate via
an AS-Interface.
