The 3ABD00038131-D: Normal-use (Pn 55 kW, In 96 A) covers constant-torque applications like conveyors and pumps at full rated current. Heavy-duty (PhD 45 kW, IhD 77 A) applies to high-starting-torque loads such as crushers or extruders where the drive must deliver peak torque for longer periods. Light-overload (PlD 55 kW, IlD 91 A) is for variable-torque fans and centrifugal pumps where the current profile stays below the normal-use continuous rating.
Enclosure and mounting — panel fit
Wall-mounted, IP21, NEMA 1. Suitable for indoor, non-hazardous locations where drips and falling dirt are the main concern. The R6 frame size determines gland plate entry and DIN-rail or backplate bolt pattern — verify panel depth for cable bend radius at the bottom entry. NEMA 1 means no conduit knockouts; you bring your own cable glands through the bottom plate.
