5 free engineering tools for drive technology and embedded development

Primary tool

Calculate Cable Cross-Section

Determine the correct cable cross-section for your system, based on current, cable length, and permissible voltage drop. The tool supports DC, AC single-phase and three-phase.

✓ The minimum cross-section is automatically determined according to IEC 60364.
✓ The current carrying capacity check covers both copper and aluminum.
✓ mm² and AWG are converted synchronously.
✓ DC, AC single phase, and three phase are covered in a single tool.
