ABB article 3BHB012961R0001 is paired with semiconductor designation 5SHX 2645L0002. In ABB semiconductor nomenclature, 5SHX denotes a reverse-conducting IGCT; the complete suffix and gate-unit assembly must match the converter parts list. Use it only in the medium-voltage converter stack documented for this complete IGCT assembly. Match both codes, 4.5 kV class marking if present, gate unit, clamp force, cooling stack, snubber components, polarity and converter position.
3BHB012961R0001 5SHX 2645L0002 must be selected from the complete manufacturer identity and the receiving-system evidence. Use it only in the medium-voltage converter stack documented for this complete IGCT assembly. Discharge and earth the DC link, protect the gate unit and optical connections, and use the specified clamp and cooling procedure.
Use the ABB assembly article and complete 5SHX device designation together.
Confirm gate-unit type, optical links, polarity and protective feedback from the converter parts list.
Apply specified clamp force and cooling-stack procedure, then monitor temperatures during staged loading.
ABB semiconductor nomenclature uses 5SHX for reverse-conducting IGCT devices. The remaining code identifies the electrical/mechanical execution; therefore 5SHX 2645L0002 cannot be replaced from voltage/current class alone.
The IGCT, gate unit, optical command link, clamp, cooling plates and snubber network form one low-inductance switching assembly. Verify polarity and clamp force, then perform gate and insulation checks before staged converter energization.
Availability and lifecycle status are confirmed for the exact 3BHB012961R0001 5SHX 2645L0002 article at quotation.
Moore Automated verifies the supplied condition, included items and installed-system match against the complete manufacturer identity.
The replacement must be commissioned with the checks listed in the technical sections.
