Key benefits

Save space

SIRIUS contactors enable compact control cabinets with high packing density. In sizes S00 to S3, the contactors even have the auxiliary switches integrated into the enclosure.

Implement expansions easily

With integrated ranges of accessories for sizes S00 to S3 as well as S6 to S12, individual function expansions can be implemented with no great effort.

Increase reliability

Thanks to their extreme ruggedness and outstanding contact reliability, our contactors switch with dependability and trustworthiness.

Featured capabilities

Use for large currents

SIRIUS 3RT contactors up to 2,650 A - the perfect combination for wind turbines or converters.

Efficient wiring of switchgear

Trying to determine which connection technology to use for your switchgear? We will show you how to connect and install your switchgear quickly and without errors.

Failsafe control input

SIRIUS contactors can be directly controlled from failsafe controllers. While higher power ranges generally require a coupling level due to higher power consumption, the coupling level can be eliminated for these new contactors.
