Description
1. Product Description
The ABB 5SHX1960L0004 is a high-power Insulated Gate Commutated Thyristor (IGCT) module designed for medium-voltage (MV) and high-power industrial applications. As a key component in power electronics systems, the 5SHX1960L0004 combines the high current-carrying capacity of thyristors with the fast switching capabilities of IGBTs, making it ideal for demanding applications such as motor drives, static var compensators (SVCs), and high-voltage direct current (HVDC) converter stations. Its robust design, based on ABB’s advanced IGCT technology, ensures low conduction and switching losses, high reliability, and excellent thermal cycling performance. The module supports direct series connection with simplified voltage balancing using resistors and RC snubbers, enabling stable operation under critical conditions like temperature variations and component tolerances.

6. Selection Recommendations
- Voltage/Current Matching: Ensure the module’s 4.5 kV/1960 A rating aligns with your system’s peak requirements.
- Cooling Strategy: Choose air/water-cooled variants based on ambient temperature and space constraints.
- Redundancy: For critical systems, use 1+1 redundancy (as demonstrated in HVDC projects).
- Compatibility: Verify interface standards (e.g., gate drive compatibility with ABB’s generation A/B units).
7. Precautions
- Thermal Management: Ensure adequate heat dissipation (e.g., heatsinks or cooling systems) to maintain <85°C operating temperature.
- Drive Circuit Design: Use ABB-recommended gate units (e.g., 3BHL000390P0104) for optimal switching performance.
- Safety Compliance: Follow IEC 60747-5-1 standards for high-voltage installations.
- Maintenance: Inspect for mechanical stress (e.g., contact pressure in press-pack modules) every 2 years.
