For accurate dimensioning, use the Win-Soft Starter selection and simulation program. We will check the case and contact you as soon as possible. The measurement error is documented on a calibration certificate, which serves as proof.
Spring-loaded connection busbar adapter: During starting, these devices limit the torque as well as the current and prevent the shocks which arise during direct starts or wye-delta starts. This facilitates diagnostics and maintenance, and it shortens response times for service purposes. Fourkey operation and plain-text displays for each menu point guarantee full clarity at every moment of the parameterization and operation. S12 3RW49 PB00 1 unit 0.
If the ramp-down function “DC braking” is selected, a braking contactor must be used in addition see table for type. Your message has been sent. Thanks to their communication capability and their programmable control inputs and relay outputs the SIRIUS 3RW44 soft starters can be very easily and quickly integrated in higher-level controllers. These manifold combination options facilitate the effortless realization of your individual control cabinet solution — perfectly matched to your application.
The space required by the compact SIRIUS 3RW30 soft starter is often only about one third of that required by a contactor assembly for wye-delta starting of comparable rating.
Siemens recommends the use of the selection and simulation program Win-Soft Starter.
90kW Soft Starter S6 162A 230Vac
As an option 3rw056-6bb44 thyristors can also be protected by SITOR semiconductor fuses from short-circuiting so that the soft starter is still functional after a short-circuit type of coordination 2. This not only enables the two-phase starting of motors up to Hp at V but also avoids the current and torque peaks which occur e.
OK, I understand – continue. Soft starters rated up to Hp at V for standard applications in three-phase networks are available. The bypass contacts of these soft starters are protected during operation by an integrated solid-state arc quenching system. This reliably prevents heating of the switchgear environment.
The reading and accuracy of the instruments may change over time. HPs are for reference only. Control supply voltage [A] 0. These templates contain all the parameters which are needed for the parameterization. They reliably mitagate the sudden torque applications and current peaks during motor starting and stopping.
The output 2 must be switched over to “DC braking contactor”. We may contact you regarding your error report for clarification. Soft starters reduce this starting current by means of their voltage ramp. Function Equipped with modern, ergonomic user prompting the SIRIUS 3RW44 soft starters can be commissioned quickly and easily using a keypad and a menu-prompted, multi-line graphic display with background lighting.
S0 Spring-loaded 1 pc. The price for the calibration service is already included in the final price for calibrated version. The optimized motor ramp-up and ramp-down can be effected quickly, easily and reliably by means of just a few settings with a previously selected language.
This is notable in particular for higher motor ratings which are only rarely available as fully wired solutions. In order to reduce time and costs — and especially to minimize downtimes — we offer you a wide range of pre-wired starter solutions: What do I receive if I choose a calibrated product at Distrelec? Win-Soft Starter selection and simulation program With this software, you can simulate and select all Siemens soft starters, taking into account various parameters such as mains properties, motor and load data, and special application requirements.
Certain styles may deviate from values indicated. All orders for calibrated items are non-cancellable and non-returnable.

The Intertek calibration certificates include: If you find a product of interest without a calibration version, our customer support will be more then helpful to clarify this topic for you. The advantages of Soft Starter ES: You can find further information on the Internet at: Star-Delta Starters data sheets.
On two-phase mwnual soft starters the current resulting from superimposition of the two controlled phases flows in the uncontrolled phase. For further information, please refer to the catalog. And even inrush current peaks are reliably avoided thanks to adjustable current limiting. No track and trace will be send to the client.
