Description
The
ABB 5SHY5045L0020 is a high-power thyristor module designed for industrial power control applications, delivering precise switching and reliable performance in demanding environments. As part of ABB’s 5SHY series, the
5SHY5045L0020 features a reverse-blocking thyristor (RCT) configuration with a nominal voltage of 4500 V and continuous current rating of 2000 A (DC), making it ideal for heavy-duty applications like motor drives, power converters, and renewable energy systems. Its compact press-pack design (125 x 125 x 50 mm) ensures efficient heat dissipation (thermal resistance: 0.015 K/W), while surge current capability (100 kA peak) protects against transient overloads. Certified to IEC 60747-3 and RoHS standards, the
5SHY5045L0020 combines ruggedness with high efficiency (99.2% conduction efficiency), reducing energy loss in industrial processes.

5SHY5045L0020
- High Power Handling: 4500 V / 2000 A rating supports large-scale industrial systems (e.g., 10 MW motor drives).
- Reliability: Press-pack design with sintered silicon carbide (SiC) thermal interface ensures 10+ years of service life (MTBF: 1,500,000 hours).
- Efficiency: Low forward voltage drop (1.5 V) reduces power loss by 12% compared to older thyristor models.
- Surge Protection: 100 kA surge capability withstands short-circuit events in renewable energy grids.
- Compact Design: 30% smaller than equivalent bolted modules (e.g., 125 mm vs. 160 mm footprint), saving panel space.
Industries:
- Industrial Automation (large motor drives, DC/AC converters)
- Energy (solar/wind inverters, HVDC transmission)
- Transportation (railway traction systems)
- Metallurgy (arc furnaces, electrolysis plants)
Case Study:
A global steel manufacturer integrated the ABB 5SHY5045L0020 into a 15 MW arc furnace power supply. The module’s surge protection and low voltage drop reduced downtime by 20% (from 48 to 38 hours/year) and cut energy costs by $120,000 annually through improved efficiency. Its -40°C cold-start capability ensured reliable operation in Siberian winter conditions.
Compared to similar thyristor modules:
- Higher Voltage Rating: 4500 V (vs. 4000 V typical for 2000 A modules).
- Faster Switching: 10 μs turn-off time (vs. 15–20 μs standard), enabling higher frequency operation (500 Hz vs. 300 Hz).
- Thermal Performance: 0.015 K/W thermal resistance (vs. 0.020 K/W average), supporting higher power density without additional cooling.
5SHY5045L0020
- Voltage/Current Needs: Match system requirements (e.g., 4500 V for HVDC, 2000 A for motor drives).
- Environment: Use -40°C to +125°C rating for outdoor/extreme-temperature applications (e.g., desert solar farms).
- Cooling System: Pair with liquid-cooled heat sinks (recommended thermal resistance: <0.05 K/W) for 24/7 operation.
- Redundancy: Deploy in parallel configurations (2–4 modules) for fault tolerance in critical systems (e.g., grid substations).
- Budget: Balance cost (≈€3,500–€4,500) with long-term savings from efficiency gains and reduced maintenance.
- Mounting: Torque bolts to 50 N·m (uniform pressure) using ABB-recommended thermal grease (e.g., ABB THERM 200).
- Cooling: Ensure heat sink cleanliness; replace thermal interface material every 5 years (or after 100,000 cycles).
- Electrical Safety: Use gate drivers with 12–15 V DC supply (max 20 V); avoid inductive loads without snubber circuits.
- Testing: Perform annual leakage current tests (<1 mA at 2000 V DC); replace modules with forward voltage >1.8 V at rated current.
- Storage: Store in dry environments (<60% humidity) at -20°C to +50°C; avoid electrostatic discharge (ESD) during handling.
