6. Selection Suggestions

• Voltage/Current Requirements: Match system ratings (e.g., 4500 V DC bus systems).
• Cooling Infrastructure: Ensure adequate cooling (liquid preferred for 4000 A loads).
• Space Constraints: Leverage compact press-pack design for high-density installations.
• Cost vs. Performance: Balance upfront investment with long-term energy savings (ROI within 3–5 years for large systems).

7. Precautions

• Thermal Management: Maintain case temperature ≤85°C to avoid derating.
• Assembly Torque: Follow ABB’s torque specifications (12–15 N·m for clamping systems).
• Surge Protection: Use snubber circuits to mitigate voltage spikes during switching.
• Storage Conditions: Store in dry environments (≤60% humidity) to prevent corrosion.
