The ABB 5SHX1960L0004 is an original genuine Integrated Gate-Commutated Thyristor (IGCT) power semiconductor module developed exclusively for ABB ACS1000 and ACS2000 series medium voltage variable frequency drives, serving as the core switching component for 3.3kV industrial medium-voltage converter power units worldwide. As a flagship high-voltage power device from ABB’s power electronics division, it combines the ultra-high voltage withstand capacity and low conduction loss of conventional thyristors with the rapid turn-off responsiveness of high-grade IGBT chips, perfectly balancing heavy overload endurance and precise dynamic switching performance. All products are original factory-manufactured, fully In Stock with Fast Global Shipping for maintenance replacement and new medium voltage drive retrofit projects across steel mills, chemical factories, power plants and mining industries.

Detailed Core Technical Specifications

In standard electrical parameters, its repetitive peak blocking voltage (VDRM) reaches 6500V, with rated continuous on-state average current of 1900A under 85℃ base plate temperature, and maximum instantaneous surge current tolerance up to 6000A to resist startup inrush and unexpected load current spikes. The typical turn-off time is controlled below 1.2μs, supporting stable medium-frequency switching operation and cutting system switching loss drastically, enabling the overall medium voltage drive conversion efficiency above 98%. Matching dedicated GDU model 3BHL000390P0104 via fiber-optic communication, the module achieves complete electrical isolation between high-power main circuit and low-voltage control loop to suppress EMI interference, with real-time feedback of overvoltage, overcurrent and overtemperature fault signals via proprietary ABB drive communication protocol.
For mechanical and thermal indexes, the module adopts advanced flat ceramic sealed packaging with integrated high-conductivity copper baseplate; overall dimension is 190mm×140mm×40mm and net weight 2.6kg, designed for bolt fastening and direct water-cooled heat sink installation for efficient heat dissipation. Its rated junction operating temperature ranges from -40℃ to +125℃, storage temperature spans -55℃~+150℃ to adapt severe high-temperature, damp and dusty on-site industrial environments. Certified by CE and UL international industrial safety standards, every finished module passes strict high voltage withstand, accelerated aging and short-circuit durability tests before factory delivery under ABB full lifecycle quality management system. Built-in multi-layer hardware protection logic automatically locks switching signals during short-circuit, overheat and abnormal DC bus voltage to prevent permanent damage to medium voltage power units.

Structural Design & Application Advantages

The modular standardized structure simplifies on-site disassembly, replacement and system maintenance, greatly shortening equipment downtime during drive breakdown repair. It is the standard spare core component for ABB original medium voltage inverters, widely deployed in heavy industrial production equipment: inside steel rolling production lines, it controls main drive inverters of large rolling mills to realize stepless speed regulation and improve finished steel processing accuracy; in petrochemical industry, it drives large centrifugal compressors and industrial process pumps for energy-saving variable-speed control; besides, it is also applied in thermal power plant primary and auxiliary fans, mine hoist medium voltage converters and new energy grid-connected high-power rectifier devices.
Thanks to ABB’s decades of mature IGCT semiconductor R&D technology accumulation, 5SHX1960L0004 features outstanding long-term operational stability and ultra-low failure rate, helping global end users reduce medium voltage drive whole-life maintenance cost and realize energy-saving transformation of heavy industrial production lines. Current abundant original inventory supports quick dispatch to global clients for emergency spare part replenishment and medium voltage drive upgrading renovation.
