Description
1. Product Description
The ABB 5SHY35L4520 is an asymmetric IGCT module with a rated voltage of 4500 V and current of 4000 A (RMS), optimized for medium-frequency operations. Its press-pack design and planar technology ensure low thermal resistance (0.01 K/W) and robust surge current capability (50 kA, 10 ms). Key features include snubberless turn-off capability, high electromagnetic immunity, and a simple control interface with status feedback. Compatible with AC/DC supply voltages, the module supports series connection for scalable power systems. Built for harsh environments (-40°C to +125°C), it integrates advanced fault protection and diagnostic functions.

6. Selection Recommendations
- Power Requirements: Suitable for systems requiring 3500–4500 A RMS and 4000+ V.
- Cooling Systems: Pair with ABB liquid-cooled heat sinks for continuous high-duty cycles.
- Environment: IP65 enclosures recommended for outdoor/harsh environments.
- Scalability: Series connection capability for voltage-doubling in HVDC applications.
7. Precautions
-
Installation: Torque mounting bolts to 25–30 N·m (verify with ABB torque guidelines).
-
Cooling: Maintain heat sink temperature <85°C (liquid cooling mandatory for full load).
-
Voltage Spikes: Use surge protection devices (SPDs) for transient voltage suppression.
-
Maintenance: Inspect contact pressure annually; replace every 15 years (expected lifecycle).
