Function
The space required by the compact SIRIUS 3RW30 soft starter
is often only about one third of that required by a wye-delta
assembly 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.
At the same time the number of cables from the starter to the
motor is reduced from six to three. Compact dimensions, short
start-up times, easy wiring and fast commissioning make
themselves felt as clear-cut cost advantages.
The bypass contacts of these soft starters are protected during
operation by an integrated solid-state arc quenching system.
This prevents damage to the bypass contacts in the event of a
fault, e.g. brief disconnection of the control voltage, mechanical
shocks or life-related component defects on the coil operating
mechanism or main contact spring.
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. On two-phase
controlled soft starters the current resulting from superimposition
of the two controlled phases flows in the uncontrolled phase.
This results for physical reasons in an asymmetric distribution of
the three phase currents during the motor ramp-up. This
phenomenon cannot be influenced, but in most applications it is
non-critical.
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 %. The control
method used for these soft starters eliminates these direct
current components during the ramp-up phase and prevents the
braking torque which they can cause.

It creates a motor ramp-up that is uniform in speed, torque and
current rise, thus permitting a particularly gentle, two-phase
starting of the motors. At the same time the acoustic quality of
the starting operation comes close to the quality of a three-
phase controlled soft starter. This is made possible by the on-
going dynamic harmonizing and balancing of current half-waves
of different polarity during the motor ramp-up. Hence the name
"polarity balancing".
