Contactors for Switching Motors

Air and Vacuum Contactors

The three-pole 3RT10 contactors are admirably suited for one of the most generally encountered applications – switching 3-phase motors. The complete power range from 3 to 250 kW/400 V, for AC as well as DC operation, is covered by just seven sizes. For applications where an extremely high electrical service life is important, for heavy-duty starting or for applications with 1000 V the 3RT12 vacuum contactors are the right choice.

SIRIUS 3RT contactors in sizes S6, S10 and S12 offer you flexibility unknown up to now: coils can be lifted out and replaced in the fitted contactor without tools or removing the main wiring.

The coils which are available as conventional UC drives, electronic UC drives with or without remaining service life reporting or additionally with the AS interface communication interface can be used both for air and vacuum contactors.
