Fuji FRN050AR1L-5U FRENIC-HVAC VFD, 575V 3PH 50HP UL/NEMA 12

The Fuji FRN050AR1L-5U is a FRENIC-HVAC variable frequency drive rated for 3-phase 575V input, 50HP output, in a UL/NEMA Type 12 enclosure. That Type 12 rating means it's built for indoor environments with dust, dirt, and dripping non-corrosive liquids — think mechanical rooms, pump houses, or rooftop units where the drive sits near the equipment it controls, not in a conditioned control room.
