This is the 460V variant of the same platform as the R433HP60-230 — same compressor, same tank, different motor wiring. If your facility runs 460V 3-phase power, this is the configuration you need. Do not order the 230V unit and try to adapt it. Confirm your panel voltage before purchasing.\u003c\/p\u003e\n\n\u003cp\u003e460V 3-phase is common in manufacturing plants, larger commercial garages, agricultural facilities, and industrial buildings. If your shop has 460V service, the 460V motor variant runs at roughly half the amperage of the equivalent 230V motor — smaller wire gauges, smaller breakers, and less voltage drop on long runs from the panel to the compressor location.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eNote: The R433HP60-460 was not listed individually on Castair's website at time of writing.
