Switch and protect with SIRIUS and be IE3/IE4-ready

SIRIUS switchgear and protection devices already meet the stringent demands for switching of highly-efficient IE3/IE4 motors with their customary high availability levels, and will continue to do so in the future, in line with the newly-introduced AC-3e utilization category. For both new systems and upgrades with highly-efficient IE3/IE4 motors in combination with SIRIUS switchgear and protection devices, you will not only improve the cost-effectiveness of your system but will also make an important contribution toward reducing CO₂ levels.
