Soft StartersSwitching Devices – Soft Starters and Solid-State Switching DevicesSIRIUS 3RW Soft StartersSIRIUS 3RW Soft StartersGeneral dataGeneral dataCircuit conceptConfigurationThree-phase controlled SIRIUS 3RW soft starters can beoperated in two different types of circuit: Inline circuitThe controls for isolating and protecting the motor are simplyconnected in series with the soft starter. The motor isconnected to the soft starter with three leads. Inside-delta circuitThe wiring is similar to that of wye-delta starters. The phasesof the soft starter are connected in series with the individualmotor windings. The soft starter then only has to carry thephase current, amounting to about 58% of the rated motorcurrent (conductor current).The solid-state 3RW soft starters are designed for normalstarting. In case of heavy starting or increased startingfrequency, a larger unit must be selected. The 3RW52 softstarters may be used in isolated supply networks (IT systems)up to 600 V AC and the 3RW55 soft starters even up to 690 V.NSB0 00424L1L2L3NPENo capacitive elements are permitted in the motor feederbetween the SIRIUS 3RW soft starter and the motor(e.g. no reactive-power compensation equipment). In addition,neither static systems for reactive-power compensation nordynamic PFC (Power Factor Correction) must be operated inparallel during starting and ramp-down of the soft starter.This is important to prevent faults arising on the compensationequipment and/or the soft starter.All elements of the main circuit (such as fuses and controls)should be dimensioned for direct-on-line starting, following thelocal short-circuit conditions. Fuses and switching devices mustbe ordered separately. The harmonic component load for starting currents must be taken into consideration for the selection ofmotor starter protectors (selection of release). Please observethe maximum switching frequencies specified in the technicalspecifications.Notes:Inline circuit: Rated current Ie corresponds to the rated motor current In,three cables to the motorNSB0 00425L1L27L3For dimensioningsoft starters,starters, wewe recommendrecommend ourour SimulationSimulationdimensioning softTool for Soft6/8 orSoft StartersStarters (STS),(STS), see pagepage 7/7our TechnicalSupport:Technical My/ww/en/requests.NSOFT STARTERSPEU2L2U1T1T2V1L1V2W2W1T3L3Inside-delta circuit: Rated current Ie corresponds to approx. 58% of therated motor current In, six cables to the motor (as for wye-delta starters)Which circuit?Using the inline circuit involves the lowest wiring outlay. If the softstarter to motor connections are long, this circuit is preferable.The wiring complexity is twice as high when using the insidedelta circuit, but a smaller device can be used with the samerating. Thanks to the choice of operating mode between theinline circuit and inside-delta circuit, it is always possible toselect the most favorable solution.The braking function is possible only in the inline circuit.The inside-delta circuit cannot be used in 690 V line supplies.7/8When three-phase motors are switched on, voltage drops occuras a rule on starters of all types (direct-on-line starters, wye-deltastarters, soft starters). The infeed transformer must always bedimensioned such that the voltage dip when starting the motorremains within the permissible tolerance. If the infeedtransformer is dimensioned with only a small margin, it is best forthe control voltage to be supplied from a separate circuit(independently of the main voltage) in order to avoid thepotential switching off of the soft starter.Smart Infrastructure, Industrial Control Catalog 2021Recommended parameters for the initial commissioning of ourSIRIUS 3RW soft starters are listed in every report of ourSimulation Tool for Soft Starters (STS). In addition, ourHigh Performance soft starters provide support by means oftheir commissioning wizards.6Comparison of the types of circuitFor long starting times it is recommended to have a PTC sensoror temperature switch in the motor. This also applies for theramp-down modes torque control, pump stop and DC braking,because during the ramp-down time in these modes, an additional current loading applies in contrast to free ramp-down.

Soft StartersSwitching Devices – Soft Starters and Solid-State Switching DevicesSIRIUS3RW Soft StartersSIRIUS 3RW Soft StartersGeneral dataGeneral dataMotor feeders with soft startersThe type of coordination according to which the motor feederwith soft starter is mounted depends on the application-specificrequirements. Normally, fuseless mounting (combination ofmotor starter protector and soft starter) is sufficient.If type of coordination "2" is to be fulfilled, then semiconductorfuses must be fitted in the motor feeder.ToC1ToC2Type of coordination "1" according to IEC 60947-4-1:After a short-circuit incident, the unit is defective andtherefore unsuitable for further use (protection ofpersons and system guaranteed).Type of coordination "2" according to IEC 60947-4-1:After a short-circuit incident the unit is suitable forfurther use (protection of persons and systemguaranteed).6The type of coordination refers to soft starters incombination with the stipulated protective device(motor starter protector/fuse), not to any additionalcomponents in the feeder.The types of coordination are indicated in thecorresponding tables by the symbols shown onorange backgrounds.Feeder tests and eventsTo keep the scope of feeder tests with SIRIUS 3RW soft starterswithin economically reasonable limits, tests were conducted withfeeder components (motor starter protectors/circuit breakers,fuses) that cover the greatest number of use cases (different softstarter versions depending on, for example, line voltage, type ofcircuit, or necessary overdimensioning). For the combined teststhat were conducted, the values for the short-circuit breakingcapacity Iq in kA were determined and documented.If circuit breakers with an overload release are used (e.g. SIRIUS3RV20 motor starter protector), we recommend activating themotor protection function of the SIRIUS 3RW soft starter toprotect the motor and setting the soft starter to the rated operational current Ie of the motor. We recommend setting the circuitbreaker in such a way that it provides line protection but does notusually trip before the soft starter when a motor overload occurs.Line protection and motor protectionLine protection and motor protection are not ensured in alloperating cases, depending on: How the motor feeder is constructed (e.g. with fuses or motorstarter protectors) Whether the SIRIUS 3RW soft starters are operated within thespecification relevant for the tests (IEC 60947-4-2) Or whether the documenteddocumented constraintsconstraints (see(seepagepage7/7)6/8)havehavebeen observed.observedMotor protection by the SIRIUS 3RW soft starter is ensured forcurrents up to 8 times the rated operational current Ie in anycase. Line protection is covered by the line-side motor starterprotector/circuit breaker or fuse. These motor feeder components must be dimensioned accordingly and the cable crosssections must be chosen to match.Line protectionLine protection in motor feeders with soft starters is alwayscovered by a fuse or a circuit breaker both in case of an overloadand in case of a short circuit. The circuit breaker must have anoverload release. That is the case for motor starter protectors(e.g. SIRIUS 3RV20).Circuit breakers without an overload release (e.g. SIRIUS 3RV23motor starter protectors) must not be used because they do notprovide overload protection. The feeder tests for these weretherefore not performed. If the motor feeder with SIRIUS 3RWsoft starters is configured without a fuse, motor starter protectorsmust be used that ensure tripping on an overload.Motor protectionIf fuses are used to provideprovide protectionprotection againstagainst overloadoverload andshort circuitcircuit ofof thethe cables,cables, thethe motormotorisisprotectedprotectedbybythetheSIRIUS 3RW3RW raints(simple(simplestartingstartingconditions CLASSCLASS 10,10, listedlisted maximummaximumvaluesvalues forforstartingstartingcurrent, startingstarting ur)hour)ofofpagepage6/87/7)are observed,observed, configuredaccordingaccordingtotoIEC as described in the section about softsoft startersstarters (an(an optionaloptionalline contactorthethecontactor ditionspreconditionsarearemet,met,SIRIUS 3RWprotect3RW ononoverloadsoverloadstotoprotectthe motormotor inin anyany case.case.In other starting conditions and on heavy starting, the followingmust be considered:Trip classesTested fuseless switchgear assemblies comprising SIRIUS 3RWsoft starters and motor starter protectors only comply withCLASS 10.To configure tested motor feeders, for example, for CLASS 20 orCLASS 30, fuses must be used together with SIRIUS 3RW softstarters.Line contactorIn applications with high starting frequencies or heavy startingas of CLASS 20, we recommend combining fuses with the use ofa line contactor on the line side so that a motor overload isdisconnected by the fault signaling contact of the soft starter inany case (that is, even in rare cases in which disconnection bythe SIRIUS 3RW soft starter is no longer possible due to theoperating state of the thyristors).Smart Infrastructure, Industrial Control Catalog 20217/9SOFT STARTERSSetting the motor currentIn accordance with IEC 60947-4-2, the SIRIUS 3RW soft startersare dimensioned and checked for operation with up to 8 timesthe rated operational current Ie. For currents larger than this,reliable disconnection of an overcurrent by the SIRIUS 3RW softstarter is not ensured. Such large overcurrents have to bedisconnected by a switching device at a higher level(e.g. by a circuit breaker or a fuse in conjunction with an optionalline contactor).7If the short-circuit breaking capacity is the same, of course,smaller circuit breakers or fuses can also be used for theselected soft starter provided the dimensioning of the shortcircuit components is suitable for the connected three-phasemotor and the line protection for the cables used. For type ofcoordination "2" (with semiconductor protection), it is alsonecessary to compare the characteristics because theprotection function would no longer be completely ensured if toosmall a fuse were selected. If the soft starter does not have amotor protection function, the motor protection must also bedimensioned appropriately.There are operating states of the thyristors (caused, for example,by high starting frequencies or heavy starting) that do not permitan overload to be disconnected by the SIRIUS 3RW soft starter.These cases are very rare but can not be ruled out in all cases.
