What this packaged drive is
It's a 3-phase unit rated for 208-240 V input at 50/60 Hz, with a UL light-overload output of 7.5 Hp at 24.2 A (460 V). The NEMA Type3R enclosure is rain-tight and corrosion-resistant.
The UL light-overload rating of 7.5 Hp and 24.2 A is the number that governs motor sizing — it's not a peak surge but the continuous output under typical pump/fan duty. The 208-240 V input range covers common North American three-phase supplies; the 50/60 Hz rating means it works on both 50 Hz and 60 Hz grids without derating. The NEMA Type3R enclosure eliminates the need for a separate weatherproof enclosure, but verify that the gland plate and conduit entries match your installation — the frame size isn't listed here, so physical dimensions need a quick check against the cabinet cutout.
