Selection Suggestions and Precautions
Selection Suggestions:
- Confirm the exact voltage class (4500 V) and current rating match the application requirements.
- Ensure proper press-pack clamping force and heatsink surface quality for optimal thermal and electrical contact.
- Verify compatibility with the existing power stack or converter design (especially in ABB medium-voltage systems).
- Check the full order code (3BHL000968P3002 or equivalent) for the correct version.
Precautions:
- Press-pack devices require precise mounting pressure and flat, clean heatsink surfaces.
- Improper clamping can lead to thermal runaway or mechanical failure.
- Follow ABB application notes for cooling, snubber circuits, and gate drive (if applicable in the system).
- Handle with care — ceramic housings can be damaged by impact or uneven pressure.
- Only qualified personnel should install or replace high-power semiconductors.
- Observe all high-voltage safety procedures during installation and maintenance.
