This is a dedicated HVAC drive variant within the FRENIC family, sized for large fan and pump loads in commercial or industrial building systems. ## Deployment context As a UL open type drive, the FRN500AR1S-4U is intended for installation inside an electrical enclosure that provides the required environmental protection. The 500 HP rating at 460 V places it in the large-drive category, typically feeding centrifugal fans, cooling-tower fans, or condenser-water pumps in chiller plants and air-handling systems. Panel integration requires attention to bus-bar sizing and cooling airflow for the drive's heat sink.","metaTitle":"Fuji FRN500AR1S-4U FRENIC-HVAC, 500 HP 460V 3-Phase Drive, U","metaDescription":"Fuji FRN500AR1S-4U FRENIC-HVAC drive, 500 HP at 460V 3-phase, UL open type.
