Siemens Simotics RV Rotary Phase Converter from China

Siemens Simotics RV converts single-phase AC to three-phase AC using a rotating idler motor, enabling operation of three-phase equipment from single-phase power supplies. This mechanical-electrical rotary conversion process qualifies it specifically for HTS 8502.40.00.00 as an electric rotary converter.

Import Tips

Document phase conversion ratio and idler motor specifications to confirm rotary converter classification

Ensure labeling meets NEC requirements for phase-converting equipment to pass U.S. inspections

Avoid shipping with attached loads; declare as standalone converter to prevent generating set classification
