ABB S-093H | 3BHB030478R0009 PHASE MODULE (ACS6000 Medium Voltage Drive Phase Module)
Basic Product Information
Model: S-093H
Part Number: 3BHB030478R0009
Full Name: IGCT Phase Module
Compatible Drive: ABB ACS6000 medium voltage high-power AC drive (legacy medium voltage drive, categorized as legacy product on ABB official website)
Core Power Device: IGCT Integrated Gate Commutated Thyristor, the signature power semiconductor for ACS6000, different from IGBT modules.
Product Positioning: It serves as the core power unit on the inverter side of ACS6000. One single module functions as one phase power leg. Three identical phase modules are assembled to form a 3-phase inverter, performing DC to AC inversion to supply medium voltage motors.
The ACS6000 adopts a modular building-block architecture. The complete system consists of ARU/DRU rectifier unit, DC bus, phase modules and control unit. The S-093H is the power building block of the inverter. It supports parallel capacity expansion and works for single motor or multi-motor common DC bus solutions.
Appearance and Structure
Integrated Water-Cooled Design: The module comes with built-in water pipe connectors with bent metal inlet and outlet ports. Water cooling is standard for high-power ACS6000 units. An integrated water-cooled heat sink dissipates heavy heat loss generated by IGCT, which is the most recognizable visual feature of S-093H.
Power Terminals: High voltage DC bus terminals and AC output terminals with large copper high-voltage posts for connecting the DC bus and motor side.
Gate Driver & Monitoring Board: The bottom of the module integrates IGCT gate driver PCB, voltage/current sampling circuits and fault monitoring loops. It continuously collects operating status and sends alarms to the ACS6000 controller for overcurrent, overtemperature, IGCT failure and abnormal cooling water flow.
Mechanical Frame: Reinforced metal frame with epoxy insulation supports. It applies fuseless design as specified by ABB official documentation. Short-circuit protection is realized through fast IGCT turn-off instead of power fuses.
Installation: Drawer-style pluggable modular design mounted on cabinet rails. Individual phase module can be replaced independently during faults to reduce downtime and maintenance duration.
Core Technical Principle
IGCT Power Conversion: The S-093H consists of IGCT devices plus freewheeling diodes to form a single-phase inverter leg. DC bus voltage feeds into the module. With ABB DTC Direct Torque Control algorithm, the IGCT switches rapidly to convert DC power into adjustable amplitude and frequency 3-phase medium voltage AC for motor drive. The ACS6000 uses DTC instead of conventional V/F control, delivering ultra-fast torque response suitable for dynamic heavy-load applications such as metallurgical rolling mills.
Four-Quadrant Operation (with ARU Active Rectifier Unit): When paired with ARU active rectifier, the S-093H phase module supports four-quadrant operation. Regenerative braking energy from motors can be fed back to the grid. Systems with diode rectifiers only support motoring mode.
Built-in Protection Functions
- IGCT gate drive protection and power device overtemperature monitoring
- Phase current and DC link voltage sampling
- Fast short-circuit turn-off (fuseless protection). IGCT provides nanosecond-level hard turn-off capability, which is the core safety feature of ACS6000
- Cooling water flow and temperature monitoring; automatic lockout upon water shortage or overtemperature

Product Lifecycle & Spare Part Information
The ABB ACS6000 is a legacy medium voltage drive. ABB has stopped manufacturing new complete units, while spare parts remain available for stock sales. S-093H (3BHB030478R0009) is the official spare part number. Other phase modules in the same family include S-123H for different MVA power ratings. These models are not directly interchangeable. Always verify the exact part number 3BHB030478R0009 before replacement. Commissioning requirements after S-093H replacement: Run device verification inside ACS6000 control software, calibrate gate drive parameters and carry out cooling water circuit leak test.
Common Fault Points
- Clogged or leaking cooling water circuit → module overtemperature trip
- Aging IGCT gate driver board and fiber communication faults
- Drift of internal current sampling board triggering false overcurrent alarms
- High voltage creepage alarms caused by dust accumulation or condensation on insulation components
