The 3ABD00058857-D: Three duty ratings are on record. Heavy-duty use (PhD) 132 kW at 246 A covers constant-torque applications — conveyors, extruders, positive-displacement pumps — where the drive sees higher sustained torque at low speed. Light-overload use (PlD) also 160 kW but at 278 A, which sits between the two; useful if your load profile has occasional overloads but not the full constant-torque demand. The spread between 293 A and 246 A gives you a real sizing decision: if your motor is 160 kW but the load is a screw conveyor, you need the heavy-duty line, not the normal-duty one.
Wall-mounted, NEMA Type 1 enclosure with IP21 ingress protection. Frame size R8 is the physical footprint; if you're replacing an existing drive in a panel, check the gland plate layout against the R8 drilling pattern — the cable entry positions are specific to this frame. The IP21 rating means the bottom cable entries need to be sealed properly in the gland plate to maintain the rating.
