Selection Guide
Use the following criteria to confirm the E82EV751K4C is the right choice — or to identify the best alternative:
| Selection Criterion | Recommendation |
|---|---|
| Motor power ≤ 7.5 kW, 400 V supply | E82EV751K4C is a direct fit |
| Existing LENZE 8200 installation | Use E82EV751K4C for drop-in replacement |
| Upgrading to newer platform | Consider LENZE i550 (E55AE series) |
| PROFINET required natively | Consider Siemens G120 or ABB ACS580 |
| Harsh environment (IP55+) | Specify E82EV751K4C with external IP55 enclosure or select ABB ACS580 IP55 variant |
| Budget-sensitive replacement | Schneider ATV320 or Yaskawa A1000 offer cost-competitive alternatives |
| Safety functions (STO/SS1) required | Upgrade to LENZE i550 or Siemens G120 with safety option |
