ABB 5SHX10H6004 (3BHB003230R0101) – IGCT Gate Unit for Medium-Voltage Drives and Converters

The ABB 5SHX10H6004, order code 3BHB003230R0101, is a dedicated IGCT gate unit designed for high-power converter stacks. From my experience, this model is used alongside ABB 5SHY IGCTs in medium-voltage drives, static VAR compensators, and large industrial rectifier/inverter cabinets where fiber-optic firing and robust protection are a must. You might notice that it slots into existing ABB stacks with minimal adaptation, which is why maintenance teams typically keep one on the shelf as a form/fit/function replacement.

Our Order Placement Process and Guarantees

Key Features

• Optimized for IGCT stacks – Engineered to drive ABB 5SHY-series IGCTs used in MV drives and power converters.
• Fiber-optic firing – Fiber input/output for noise-immune triggering and isolation in high-EMI cabinets.
• Robust protection functions – Typically includes undervoltage supervision and gate-drive monitoring to safeguard the device.
• 24 VDC auxiliary supply – Common plant DC control voltage, making retrofit and service easier.
• Direct stack integration – Mechanical layout suited for stack-mounted assemblies with short, reliable gate connections.
• Service-friendly – Field-replaceable in most cabinets; fiber connectors and wiring are straightforward for maintenance teams.

Technical Specifications

Application Fields

This gate unit is typically found in:

• Medium-voltage drives (fans, compressors, pumps, rolling mills)
• STATCOM/SVC and high-power AC/DC converters
• Marine propulsion and large test benches
• Industrial power supplies and rectifier bridges using IGCT stacks

Advantages & Value

• Reliability – Designed for high di/dt environments and continuous duty; in many cases, units run for years with minimal intervention.
• Compatibility – Works with ABB IGCT-based stacks, easing replacement planning and reducing unexpected redesign work.
• Lower downtime risk – Fiber-optic isolation and built-in supervision help avoid nuisance trips under electrical noise.
• Procurement confidence – Clear ordering code (3BHB003230R0101) streamlines spares management and warehouse traceability.
• Support for lifecycle service – We can align on revision matching, basic functional checks, and packing suitable for critical spares.

Installation & Maintenance

• Cabinet environment – Install in a clean, ventilated enclosure (IEC cabinet standards). Keep ambient within 0–55 °C and avoid condensation.
• Wiring & power – Supply regulated 24 VDC. Observe correct polarity, proper protective earth, and short, secure gate leads to the IGCT device.
• Fiber handling – Clean connectors before mating; maintain minimum bend radius to preserve signal integrity.
• Safety – De-energize and discharge the DC link before work. Follow lockout/tagout and ESD protection procedures.
• Routine checks – Periodically verify connector tightness, fiber seating, auxiliary supply stability, and cabinet airflow. Firmware updates aren’t usually needed unless specified by an ABB bulletin.

Quality & Certifications

• CE conformity for industrial environments (typical for ABB gate units)
• RoHS compliance and ISO 9001 manufacturing environment
• Warranty: 365 days from delivery
