© Siemens AG 2010 Soft Starters and Solid-State Switching Devices General data Overview SIRIUS 3RW Soft Starters SIRIUS 3RF2 solid-state switching devices 4 SIRIUS 3RW soft starters permit soft starting and smooth ramp- down of three-phase asynchronous motors. Depending on the scope of functions required it is possible to choose between: • Soft starters for Standard applications • Soft starters for high-feature applications The SIRIUS 3RF2 solid-state switching devices reliably switch a wide range of different loads with alternating voltages in 50 and 60 Hz systems.

Solid-state switching devices for resistive loads • Solid-State Relays • Solid-State Contactors • Function modules SIRIUS 3RW – Service-proven in many applications Functions of the SIRIUS soft starters include: • Soft starting and smooth ramp-down • Stepless starting • Torque control and limitation Solid-state switching devices for switching motors • Solid-State Contactors • Solid-state reversing contactors Cost-efficient operation SIRIUS 3RF2 – for almost unending activity The advantages of SIRIUS soft starters at a glance:

• Reduction of current peaks • Avoidance of mains voltage fluctuations during starting • Reduced load on the power supply network • Reduction of the mechanical load in the operating mechanism • Considerable space savings and reduced wiring compared with conventional starters • Maintenance-free switching • Very easy handling • Fits perfectly in the SIRIUS modular system Conventional electromechanical controlgear is often overtaxed by the rise in the number of switching operations. A high switch- ing frequency results in frequent failure and short replacement cycles.

However, this does not have to be the case, because with the latest generation of our SIRIUS 3RF2 solid-state switch- ing devices we provide you with solid-state relays and contac- tors with a particularly long endurance - for almost unending ac- tivity even under the toughest conditions and under high mechanical load, but also in noise-sensitive areas. Proved time and again in service SIRIUS 3RF2 solid-state switching devices have firmly estab- lished in industrial applications. They are used above all in ap- plications where loads are switched frequently – mainly with re- sistive load controllers, with the control of electrical heat or the control of valves and motors in conveyor systems.

In addition to its use in areas with high switching frequencies, their silent switching means that SIRIUS is also ideally suited for use in noise-sensitive areas, such as offices or hospitals. The most reliable solution for any application Compared to mechanical controlgear, our SIRIUS 3RF2 solid- state switching devices stand out due to their considerably longer service life. Thanks to the high product quality, their switching is extremely precise, reliable and, above all, insuscep- tible to faults. With its variable connection methods and a wide spread of control voltages, the SIRIUS 3RF2 family is universally applicable.

Depending on the individual requirements of the ap- plication, our modular controlgear can also be quite easily ex- panded by the addition of standardized function modules. 4/4 Siemens LV 1 · 2010
