In the past, typical starter solutions for

standard applications were based on

direct and wye-delta* starting. Today,

the advantages offered by soft starter

solutions are increasingly utilized.

SIRIUS soft starters, for example, not

only improve the start-up behavior of

escalators, elevators, conveyor belts and

pumps, as they simply facilitate a softer

start-up than electro-mechanical starters.

Above all, they protect the drive system

and the mains supply and thus contribute

to reducing the system costs from many

points of view.

To allow for an optimum adjustment of

your drive to the application, we offer

a complete portfolio of soft starters in

various sizes for almost any application

area. For example, the two-phase-

controlled SIRIUS 3RW30 is particularly

suitable for standard applications up to

55 kW. SIRIUS 3RW40, which additionally

offers motor overload, intrinsic device

and thermistor motor protection, also

masters demanding tasks in a soft

manner within the power range from 5.5

to 250 kW.
