6. Selection Recommendations
- Power Requirements: Match 4500 V/4000 A rating to system needs; smaller applications may use ABB’s 5SHY25xx series.
- Environment: Ensure compliance with temperature (-40°C to +125°C) and altitude (≤2000 m).
- Scalability: Use stackable modules for systems >5 MW to maintain redundancy and ease of expansion.
7. Precautions
- Installation: Torque mounting bolts to 15 N·m (avoid over-tightening).
- Cooling: Maintain airflow ≥5 m/s for full-load operation; use external heat sinks for prolonged high-current use.
- Voltage Protection: Deploy snubber circuits (RC networks) to suppress voltage spikes.
- Storage: Store in dry conditions (≤30% humidity), away from corrosive gases and direct sunlight.
