| The space required by the compact SIRIUS 3RW40 softstarter is often only about one third of that required by a contactor assembly for wye-delta starting of comparable rating |
| This not only saves space in the control cabinet and on the standard mounting rail but also does away completely with the wiring work needed for wye-delta starters |
| This is notable in particular for higher motor ratings which are only rarely available as fully wired solutions |
| Compact dimensions, short start up times, easy wiring and fast commissioning make themselves felt as clear-cut cost advantages |
| The bypass contacts of these softstarters are protected during operation by an integrated solid state arc quenching system |
| The new series of devices comes with the polarity balancing control method, which is designed to prevent direct current components in 2-phase controlled softstarters |
| It leaves the set start ramp during the ramp-up the ramp gradient is fixed by the starting voltage and the ramp time as soon as the selected current limit is reached |
| From this moment the voltage of the soft starter is controlled so that the current supplied to the motor remains constant, This process is ended either by completion of the motor ramp-up or by tripping by the intrinsic device protection or the motor overload protection |
| As the result of this function the actual motor ramp-up can well take longer than the ramp time selected on the soft starter |
| Device versions with thermistor motor protection evaluation are available up to a rating of 55 kW (at 400 V), A thermoclick measuring probe can be connected directly, as can a PTC of type A |
| Thermal overloading of the motor, open circuits and short circuits in the sensor circuit all result in the direct disconnection of the soft starter, The new series of devices comes with the polarity balancing control method, which is designed to prevent direct current components in two-phase controlled soft starters |
| Controlling the power semiconductors results not only in this asymmetry, however, but also in the previously mentioned direct current components which can cause severe noise generation on the motor at starting voltages of less than 50 % |
