Conversion Made EasySIRIUS 3RW30 in DetailBelt slippage with heater blowers or sudden water pressure build-up in washingsystems are only two of many possible problems which may occur if motorsoutput too much power directly upon start-up. With the SIRIUS 3RW30, suchfailures are reliably prevented up to 55 kW (with 400 V). The main advantage:As the SIRIUS 3RW30 is the world’s only soft starter which offers identical sizeswithin one device range, it even allows for a direct conversion from direct to softstarting.10
What are the advantages of softstarting?The advantages are multiple, as theSIRIUS 3RW30 reduces the stress on themotor by reducing the start-up torqueand protects the mains against hazardouscurrent peaks through reduced currentinput. This reliably eliminates line voltagedips.What are the benefits of the SIRIUS3RW30?The SIRIUS 3RW30 is particularly compactthanks to its consistently optimizedpower components in hybrid technology.It thus also facilitates side-by-side assemblyup to 60 °C. It offers fast configurationand easy mounting with only 3 motorsupply cables. Small fuseless load feederscan be assembled with a single module –with the SIRIUS 3RV circuit breaker. Alsofused feeders can be realized in a fast andspace-saving manner in combination withSIRIUS 3RB solid-state overload relays.What about safety and reliability?Thanks to two-phase control and thepatented “polarity balancing” controlprinciple, the SIRIUS 3RW30 is adependable device which ensures safeand reliable operation. In addition,the integrated bypass contact systemreduces the soft starter‘s heat lossduring operation.What are the application areas?The SIRIUS 3RW30 can be employed inalmost any standard application up to amotor rating of 55 kW with 400 V. Forexample for driving conveyor belts, compressors,grinding machines, saws, agitators,etc.With the SIRIUS 3RW30 in size S0 (45 mm),up to 38 A can be switchedHow is the SIRIUS 3RW30 set?Ramp-up time and starting voltagecan be comfortably and easily set via2 potentiometers, ensuring optimumstarting behavior.How is the soft starter controlled?Without interface relays, the SIRIUS3RW30 can be directly controlled viathe PLC – or via the control input. Therespective operating state is signaled viaa relay output.What are the saving potentials?Space savings in the control cabinet upto 70% are achievable compared to wyedelta*starters (example 18.5 kW: 45 mmwidth instead of 158 mm). The SIRIUS3RW30 also pays off in terms of mounting:with only 3 instead of 6 motor supplycables.The 3RW30 is also available withremovable control terminals. Whenreplacing a 3RW30, the wiring on theterminal thus remains intact (“permanentwiring”) and the terminals are simplysnapped onto the new 3RW30, whichsaves a considerable amount of time.Is the SIRIUS 3RW30 affordable?Absolutely, as it not only ensures reliableoperation thanks to standardizedproduction, but is also very attractive interms of price.How about accessories?In addition to easy-to-mount terminalcovers for optimum touch protection,also box terminal blocks, connectionmodules and labeling strips from theSIRIUS range are available for the 3RW30.* star-delta11
