Sizing and duty class
The 3ABD00038132-D: Normal-use (Pn 75 kW, In 124 A) covers constant-torque loads like conveyors and pumps. Heavy-duty (PhD 55 kW, IhD 96 A) handles higher peak demands — crushers, extruders, or rapid acceleration profiles. Light-overload rating (PlD 75 kW, IlD 118 A) matches normal-use power but at slightly lower current, useful for variable-torque fans or centrifugal pumps where overload margin is less critical.
Wall-mounted, frame R6. IP21 and NEMA Type 1 mean it's suitable for indoor, dry locations — no washdown or dust-tight rating. The enclosure keeps out fingers and falling dirt, but not moisture spray or airborne dust. Plan for a filtered fan intake if the cabinet sees particulates.
