An external display and operator module can be connected by means of a connection cable to the soft starter, thus enabling active indications and the like to be read directly from the control cabinet door. Control supply voltage DC 24 V Motor starter protector f. Due to two-phase control, the current is kept at minimum values in all three phases throughout the entire starting time and disturbing direct current components are eliminated in addition.

For optimized motor starting and stopping the innovative SIRIUS 3RW44 soft starters are an attractive alternative with considerable savings potential compared to applications with a frequency converter. HPs are for reference only.

Siemens SIRIUS Modular System

The harmonic component load for starting currents must be taken into consideration for the selection of motor starter protectors selection of release. The measurement error is documented on a calibration certificate, which serves as proof. S12 3RW49 PB00 1 unit 0. Rated operational voltage Ue The SIRIUS current monitoring relays not only monitor 3r4w056-6bb44 motor, but the entire system or driven process for overcurrent and undercurrent, cable breakage and phase failure.

3RWBB44 Soft Starter 90 kW @ VAC Siemens

Device versions with thermistor motor protection evaluation are available up to a rating of 55 kW at V. Soft starters reduce this starting current by means of their voltage ramp. E-invoicing Reduce paperwork and access all invoices in one place using My Account. This also applies for the smooth ramp-down because during the ramp-down time an additional current loading applies in contrast to free ramp-down.


Screw connection Spring-loaded connection Order no. Only private customers can order as guest. Please enter your name and your e-mail address. Our expert team have over 25 years experience solving problems and providing expert advice. Rated current A Semiconductor fuses min.

P Setting Order no. Isolation contactor, space heater, ect.

Class 74 combination starters include: For easy product selection, incl. This manual can be downloaded off the internet. In the event of severe conditions or increased switching frequency, it may be necessary to choose a larger device.

For accurate dimensioning, use the Win-Soft Starter selection and simulation program. Spring-loaded connection for mounting onto DIN rail S If necessary, an overload relay for heavy starting must be selected where long starting times are involved.

Rated current Ie corresponds to the rated motor current In, 3 cables to the motor Note: Products The range of this service include, but not limited to: Fuses, controls and overload relays must be ordered separately. Comparison of the types of circuit For long starting times it is recommended to have a PTC sensor in the motor.

These types of coordination are indicated in the Technical specifications by gray backgrounds. Included in the scope of supply 3RW44 3.

The Win-Soft Starter selection and simulation program can be downloaded free of charge from: Integrated bypass contacts mean that minimal power is used at the power semiconductors thyristors after the motor has started up. Please visit our website to find instruments which can be calibrated. Manua all technical information, please consult the Industrial Controls Catalog or contact your local sales support center. This not only saves space in the control 3ew4056-6bb44 and on the standard mounting rail but also does away completely with the wiring work needed for wye-delta starters.


With the unique SIRIUS modular system, which offers everything required for the switching, protection and starting of motors and systems. Close An error occurred, your message could not be sent. Comprehensive information on Industrial Controls Amongst others, rapid and targeted provision of information on: Documents Flashcards Grammar checker.

If the soft starter to motor connections are long, this circuit is preferable.
