The 3AXD50000448548: This module carries three duty ratings, and which one you spec depends on the mechanical load profile. Normal use (Pn) delivers 2200 kW at 2300 A — that's your baseline for constant-torque applications like conveyors or pumps running at full load. Heavy-duty use (PhD) drops to 1600 kW at 1720 A, sized for loads that demand peak torque for short periods, like crushers or extruders. Light-overload use (PlD) sits at 2000 kW and 2208 A, a middle ground for variable-torque loads such as fans and centrifugal pumps. Pick the duty class that matches your actual starting and running conditions, not the highest number — the drive's thermal capacity is built around that curve.
It's a module for cabinet building with an IP00 degree of protection and an Open Type NEMA enclosure. That means it's not sealed against dust or water — it expects to live inside a clean, dry electrical enclosure where the panel itself provides the environmental barrier. The WEEE category is 4 — Large Equipment — which matters for end-of-life disposal compliance in European markets.
