3RW40
for standard applications
Overview
SIRIUS 3RW40 soft starters have all the same advantages as the
3RW30 soft starters.
The SIRIUS 3RW40 soft starters are characterized above all by
their small space requirements. Integrated bypass contacts
mean that no power loss has to be taken into the bargain at the
power semiconductors (thyristors) after the motor has started
up. This cuts down on heat losses, enabling a more compact
design and making external bypass circuits superfluous.
At the same time this soft starter comes with additional
integrated functions such as adjustable current limiting, motor
overload and intrinsic device protection, and optional thermistor
motor protection. The higher the motor rating, the more
important these functions because they make it unnecessary to
purchase and install protection equipment such as overload
relays.
Internal intrinsic device protection prevents the thermal
overloading of the thyristors and the power section defects this
can cause. As an option the thyristors can also be protected by
semiconductor fuses from short-circuiting.
Thanks to integrated status monitoring and fault monitoring, this
compact soft starter offers many different diagnostics options.
Up to four LEDs and relay outputs permit differentiated
monitoring and diagnosis of the operating mechanism by
indicating the operating state as well as for example mains or
phase failure, missing load, non-permissible tripping time/class
setting, thermal overloading or device faults.
Soft starters rated up to 250 kW (at 400 V) for standard
applications in three-phase networks are available. Extremely
small sizes, low power losses and simple start-up are just three
of the many advantages of the SIRIUS 3RW40 soft starters.
"Increased safety" type of protection EEx e according to
ATEX directive 94/9/EC
The 3RW40 soft starters size S6, S10 and S12 are suitable for
starting explosion-proof motors with "increased safety" type of
protection EEx e;

Application
The SIRIUS 3RW40 solid-state soft starters are suitable for soft
starting and stopping of three-phase asynchronous motors.
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.
This not only enables the two-phase starting of motors up to
250 kW (at 400 V) but also avoids the current and torque peaks
which occur e.g. with wye-delta starters.
