ABB 5SHX2645L0002 (3BHB012961R0001) Integrated Gate-Commutated Thyristor (IGCT) Power Module

ABB 5SHX2645L0002 is the core component part number, while 3BHB012961R0001 serves as the assembly drawing/assembly part number for the complete IGCT assembly kit, 

exclusively designed for ABB ACS6000 series medium voltage variable frequency drives.

This unit is a high-power IGCT semiconductor module integrating thyristor chip, freewheeling diode, gate driving circuit and RC absorption circuit. It executes high-speed high-voltage power 

switching, completes AC-DC rectification, DC-AC inversion and energy conversion inside medium voltage drives, realizing speed & torque regulation for large high-voltage motors.

With advantages combining low conduction loss of thyristor and fast turn-off capability of transistor, it is the indispensable core power spare part for maintenance, overhaul and fault replacement 

of mining, metallurgy, oil & gas large medium voltage drive cabinets.
