Efficient Engineering with the utmost functionality
The SIRIUS 3RA6 compact starter is an innovative addition to SIRIUS switchgear. As a universal motor feeder to IEC / EN 60947-6-2, the SIRIUS 3RA6 compact starter combines the functionality of a circuit breaker, solid-state overload relay and contactor. It can be used for all applications involving direct starting of standard induction motors up to 32 A (20HP - 460 Amp).
The SIRIUS 3RA6 compact starters fulfill all the current requirements for configuring load feeders. In this way, you profit from the SIRIUS 3RA6 compact starters with high functionality, flexibility and readily available machine concepts viable for the future, while reducing costs from configuration to commissioning.
The SIRIUS 3RA6 compact starters for IO-Link combine circuit breaker, contactor and solid-state overload relay in a single device.An optional operator panel can be connected for simple, local operating and monitoring.The IO-Link interface enables simple 3-wire connection to the higher-level controller.
The SIRIUS 3RA6 compact starters can easily be combined with SIRIUS circuit-breakers of size S00/S0 via 3-phase busbars, for example.
Advantages at a glance
Compact design offers enormous savings in space and wiring in the control cabinet
Spring-loaded and screw-type connection technology enables extremely flexible use
Removable terminals (permanent wiring) facilitate mounting and replacement
A wide variety of applications up to 32 A (20HP - 460Amp) can be implemented with only 3 wide voltage ranges and 5 wide setting ranges
Wide voltage and setting ranges keep the number of variants low (only 5 different variants for the range up to 32 A)
Optional "control kits" make wiring and testing of the direction of rotation of the motor easy, even prior to commissioning
Convenient auto reset after overload as well as clearly differentiated overload and short-circuit signaling
High plant availability ensured by integrated functionality such as welding protection of main contacts and switch-off at end of service life
For highly efficient power distribution for up to 100 Amp
The SIRIUS 3RA6 compact starter makes use of a fully pre-wired infeed system with screw-type or spring-loaded connections in the main circuit. The PE bar is already integrated so that the motor cable can be connected direct to the power distribution system thus reducing engineering overhead and space and wiring requirements.
SIRIUS circuit-breakers can also be integrated via a special adapter into the SIRIUS 3RA6 infeed system. If you wish to combine the SIRIUS 3RA6 infeed system with the latest SIRIUS 3RV19 infeed system, you simply need the optional expansion plug for quick and easy connection.
The associated 3RA6 infeed system forms an ideal basis for uniform and convenient power infeed and distribution.
Minimized wiring in the main circuit
Pluggable for extremely simple installation and removal of the SIRIUS compact starters
Direct connection of the motor outgoing feeder cable via integral PE bar possible
Removable terminals extremely facilitate replacement of SIRIUS compact starters – without having to disconnect the main circuit wiring
Connection and loop-through of infeed cables up to a cross-section of 70 mm²
Plug-in expansion modules and additional slots offer flexible expansion options up to a width of 1.2 meters
Harmonious interaction of all SIRIUS switchgear components thanks to perfect integration
The SIRIUS Modular System is easily connected via the SIRIUS 3RA68 and 3RV29 Infeed Systems. Individual circuit breakers, complete load feeders as well as Compact Starters are simply clicked into the infeed systems. Alternatively, conventional wiring is also possible via parallel wiring, 3-phase comb busbar or 8US busbar adaptor.
The SIRIUS 3RA6 compact starter with an IO link provides a convenient, point-to-point connection to the control level. Diagnostic data – such as end of service life, end position etc., is not simply indicated on the compact starter itself but transferred to the higher-level controller via the IO link. The outcome: high system availability and greatly reduced wiring overheads in the control circuit coupled with full integration in Totally Integrated Automation.
Large quantity of information per device in the control cabinet
Higher information density through information bundling of up to 4 starters (reversing and direct-on-line starters) on only one standard line
Convenient control from the cabinet door thanks to the optional operator panel
Fast and standardized configuration via Port Configuration Tool in STEP7
Integration in Totally Integrated Automation
Integration in automatic landscape through AS-Interface
The SIRIUS 3RA6 compact starter can be integrated in Totally Integrated Automation simply by connecting the optional AS-i mounting module to AS-Interface. The yellow two-wire AS-i cable can be used to transmit the status and diagnostics messages of the 3RA6 compact starter to the controller in a fast and simple manner – and with minimum wiring overhead.
AS-Interface reduces wiring in the control circuit considerably
Extremely simple integration in AS-Interface as installation of optional AS-i mounting module requires no tools
AS-i mounting module with A/B technology enables linking of up to 62 SIRIUS compact starters with AS-Interface
Standardized assignment of inputs and outputs keeps software programming overhead low
Different AS-i mounting modules available
