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
