3RW4073-6BB45
3RW4073-6BB45 is the smallest model in this batch with a rated current of 230A, corresponding to a voltage range of 400 to 600V AC, an insulation voltage of 600V, and complies with IEC 60947-4-2 pollution level 3 standard.
Product Positioning
The 3RW4073-6BB45 is a model with a smaller current specification in the Siemens SIRIUS 3RW40 series. It is suitable for three-phase motors with high voltage ratings of 400 to 600V AC and reduces the starting inrush current by using a voltage ramping method.
Core Product Advantages and Features
230A rated current
With a rated power of 160kW at 500V, it is suitable for medium-sized pumps, compressors and fans.
Suitable for 400 to 600V AC
The main circuit can be used in systems with higher voltage levels, broadening the selection for different power grid specifications.
Pollution Level 3 Certification
It complies with IEC 60947-4-2 pollution level 3 standards and is suitable for harsh industrial power distribution environments.
Screw terminal secure
