Selection notes - The general description mentions 660 V and 32–6300 A. The detailed section lists AC 400 V and adds N models starting at 16 A. Verify the exact frame, voltage and controller.
- The 63N model appears in both N tables with different short-time withstand figures. The original tables are preserved separately. Confirm the applicable configuration.
- The NA table leaves the 125NA 4P weight blank.
