It operates on a 3-phase 380–500 V input, 47.5–63 Hz, and is enclosed to IP55 / NEMA 12. Frame size R4.
Three duty ratings are listed: normal use (Pn 37 kW, In 73 A), heavy-duty use (PhD 30 kW, IhD 61 A), and light-overload use (PlD 37 kW, IlD 68.4 A). For a pump or fan with a quadratic torque curve, the normal-use figure governs selection. For a constant-torque load like a conveyor or extruder, the heavy-duty rating is the one that determines headroom — 30 kW / 61 A is the continuous limit under that duty class. The light-overload rating sits between the two, at 68.4 A, and is useful when the load profile has occasional peaks but stays below the normal-use current.
