The Original ABB 3BHB003154R0101 IGCT Module Spare is an ABB IGCT-based power module for the ABB ACS 600 medium-voltage drive family, where the integrated gate-commutated thyristor (IGCT) stage performs the high-power switching of the drive’s power converter.
Key Features
- IGCT power-module technology — integrated gate unit with low on-state losses (ABB StakPak/IGCT platform)
- Designed for the ABB ACS 600 medium-voltage drive (3.3–4.16 kV class drives)
- 4.5 kV-class off-state voltage (V_DRM 4500 V typical for 5SHX1960-class IGCTs)
- Press-pack design with double-sided cooling; fails into a stable shorted state
- High power density, high load-cycling capability
- Liquid-cooled for MV-drive duty
- Made in Sweden

Installation Notes
- Only qualified MV-drive service personnel may handle the IGCT module; observe the drive’s high-voltage isolation and discharge procedures.
- Confirm the exact module code (gate driver vs. IGCT device) and its position in the power stack against the drive documentation before ordering a replacement.
- Check the liquid-cooling circuit (flow, conductivity, pressure) — an IGCT stage depends on proper cooling; never energize without coolant flow.
- Handle the press-pack module with correct mounting torque and surface cleanliness; follow ABB’s assembly instructions for the clamping stack.
- After replacement, verify gate-pulse signals and perform a controlled test run per the drive commissioning procedure.
Common Questions
What is an IGCT and why is it used in the ACS 600? The Integrated Gate-Commutated Thyristor combines thyristor-like low conduction losses with forced gate commutation, giving clean turn-off at high power — the switching element of ABB’s medium-voltage drive power stages.
What voltage class does it suit? 4.5 kV-class IGCT, typical for 3.3–4.16 kV medium-voltage drives.
How is it cooled? Liquid-cooled via the drive’s cooling circuit (press-pack, double-sided cooling) — per supplier data and ABB IGCT platform practice.
