Description
The
ABB 5SHY35L4512 is a robust thyristor module with a rated voltage of 4500 V and current of 3500 A (RMS), optimized for heavy-duty industrial use. Its planar technology and press-pack design ensure low thermal resistance and long-term stability, making it suitable for harsh conditions (-40°C to +125°C). Key features include surge current capability (50 kA), fast switching times, and compatibility with ABB’s modular cooling systems. The module integrates advanced overvoltage protection and diagnostic capabilities, enabling seamless integration into AC/DC conversion systems.

5SHY35L4512 3BHE014105R0001 5SXE08-0166
- High Power Density: 3500 A RMS in a compact design (20% higher current density than legacy models).
- Rugged Reliability: MTBF > 100,000 hours (ABB testing), with resistance to vibration and thermal cycling.
- Energy Efficiency: Low forward voltage drop reduces power losses by 15% compared to standard thyristors.
- Modular Design: Easy integration with ABB’s cooling solutions (e.g., liquid-cooled heat sinks).
- Safety Features: Built-in short-circuit protection and redundant gate drive interfaces.
Industries: Metals (aluminum smelting), energy (HVDC converters), transportation (rail traction), and industrial automation.
Case Study: A steel mill in Germany reduced downtime by 30% using the 5SHY35L4512 in its arc furnace power supply. The module’s surge current handling and rapid fault recovery minimized production interruptions.
Compared to similar thyristor modules:
- Higher Voltage Rating: 4500 V vs. typical 4000 V in 竞品.
- Lower Thermal Resistance: 0.01 K/W (10% better than market averages).
- Longer Warranty: 5-year warranty (vs. 3 years industry standard).

5SHY35L4512 3BHE014105R0001 5SXE08-0166
- Power Requirements: Ideal for systems requiring 3000–4000 A RMS and 4000+ V.
- Cooling Systems: Pair with ABB’s liquid-cooled heat sinks for optimal performance in high-duty cycles.
- Environment: Suitable for outdoor/harsh environments with IP65 enclosures.
- Compatibility: Ensure alignment with ABB’s thyristor driver boards (e.g., 5SDD/5SSH series) for full functionality.
-
Installation: Torque mounting bolts to 25–30 N·m (avoid over-tightening).
-
Cooling: Maintain heat sink temperature <85°C (liquid cooling recommended for continuous operation).
-
Voltage Handling: Use snubber circuits to mitigate voltage spikes (recommended: 10 Ω/100 µF per module).
-
Maintenance: Inspect contact pressure annually; replace modules every 15 years (expected lifecycle).
