Description
ABB 5SHY45L4520 IGCT Module – Reliable high-power switching for medium-voltage converters
The ABB 5SHY45L4520 is an IGCT (Integrated Gate-Commutated Thyristor) press-pack device built for heavy-duty power conversion. From my experience, this series is typically selected when engineers need fast turn-off capability with very low conduction losses at high current levels—think medium-voltage drives, STATCOM/SVC, and traction where downtime is expensive and thermal headroom really matters. You might notice that it drops into existing ABB press-pack stacks with standard clamping hardware, making retrofit projects far less painful.

Application Fields
- Medium-voltage drives for mining, cement, oil & gas compressors, and marine propulsion
- FACTS/Utility systems: STATCOM, SVC, and grid-tied VAR compensation
- Traction propulsion and auxiliary converters
- Wind and industrial power converters where high current and reliability are key
- High-power test benches and pulse power supplies
Advantages & Value
- Reliability under stress: Press-pack architecture handles thermal and electrical cycling better than many module styles.
- Compatibility: Fits established ABB IGCT stacks and gate units, typically reducing engineering effort.
- Operational efficiency: Lower conduction losses can translate into cooler operation or headroom for overloads.
- Lifecycle support: We help match gate units, snubbers, clamps, and thermal hardware to shorten commissioning time.
- Risk reduction: Sourced from traceable channels with inspection on arrival; DOA replacement is straightforward.
One thing I appreciate is how maintenance teams can swap a press-pack IGCT in a stack within a planned stop. A customer in a rolling mill application mentioned they saw fewer nuisance trips after moving from legacy GTOs to this IGCT family—seems to be the cleaner turn-off behavior and tighter gate control.
Installation & Maintenance
- Cabinet & environment: Install in a clean, dry cabinet meeting industrial MV standards; ensure adequate ventilation or liquid-cooled heat sinks.
- Clamping force: Use a calibrated press system to apply the axial clamping force specified by ABB; verify planarity and surface cleanliness.
- Wiring: Keep gate-cathode leads short and shielded as recommended by the gate unit manual; observe creepage/clearance for MV.
- Thermal interface: Apply approved contact foil or grease if specified; check heat sink flatness and roughness.
- Safety: Lock-out/tag-out, discharge DC-link capacitors, and confirm isolation before handling.
- Routine checks: Inspect stack clamping torque, clean dust paths, verify gate unit health, and update firmware where applicable.
- Commissioning tests: Gate signal integrity, partial-discharge checks where applicable, and thermal imaging under load during trial runs.
Quality & Certifications
- Manufactured under ABB quality systems (typically ISO 9001)
- RoHS compliance in most cases for semiconductor devices (confirm per lot)
- Device-level CE/UL marking may not apply to discrete semiconductors; system-level compliance required
- Standard 12‑month warranty through our channel
Supporting Components We Can Supply
