The 3AXD50000761067: The enclosure is IP55 with a NEMA Type12 rating, so it handles hose-down and dust in pump rooms or treatment-plant walls without an extra cabinet.
The light-overload figure (7.5 A, 2 Hp) gives headroom for variable-torque centrifugal pumps that rarely pull full current. Match your motor nameplate to the heavy-duty column unless the pump curve is squarely variable-torque. Input voltage is 208... 240 V three-phase — common in North American light-industrial panels. The 50/60 Hz rating means it ships for either grid frequency; no configuration change needed at the terminals.
