Description
SIEMENS 55KW SIRIUS 3RW40 Soft Starter 3RW4047-1BB14 Circuit Breaker Softstarters 106A 55KW 400V New
Overview
The SIRIUS 3RW40 Basic Performance soft starters are suitable for soft starting and stopping of three-phase asynchronous motors. Thanks to 2-phase control, not only is the current kept at minimum values in all three phases throughout the entire ramp-up time, but interfering direct current components are also eliminated. This not only enables the 2-phase starting of motors up to 55 kW (at 400 V), but also avoids the current and torque peaks that occur, for example, with wye-delta starters
SIRIUS 3RW30/40 soft starters are the world's most compact two-phase controlled soft starters in the power range from 1.5 kW (at 400 V) to 250 kW (at 400 V) thanks to their innovative control principle. Their compact design helps you save space in the control panel configurations. SIRIUS 3RW30/40 soft starters are the ideal solution for simple applications of all kinds. The 3RW soft starters should always be designed on the basis of the required rated operational current of the motor. The motor ratings listed in the selection and ordering data are rough guide values and designed for basic starting conditions (CLASS 10).
The 3RW4047-1BB14 is a 480V-rated control module from Siemens, designed for use in pneumatic systems. It has a maximum operating temperature of 60°C and a minimum operating temperature of -25°C. The module is rated for 106A of current and has a control voltage of 230V. It is packaged in a 200-case type and measures 188mm in length and 170mm in overall depth. The module is rated for use in IP00 environments.

Functional principle of the SIRIUS 3RW30 and 3RW40 soft starters
The SIRIUS 3RW30 and 3RW40 soft starters have two antiparallel thyristors in two out of the three phases. One thyristor for the positive half-wave and one for the negative half-wave is provided in each phase (refer to Fig. "Phase angle control and schematic diagram of a two-phase controlled soft starter with integral bypass contacts"). The current in the third, uncontrolled phase is the sum of the currents in the controlled phases.
The rms value of the motor voltage is increased (from a settable starting voltage) to the rated motor voltage within a definable starting time by means of the phase angle control.
The motor current changes in proportion to the voltage applied to the motor. As a result, the starting current is reduced by the factor of this voltage.
There is a quadratic relationship between the torque and the voltage applied to the motor. As a result, the starting torque is reduced quadratically in relation to this voltage.
