Why Factories Trust Schneider’s ISFT250 Fuse?
At a Shanghai wind turbine plant, 23 unexpected voltage spikes paralyzed production lines last year – until they installed Schneider Electric’s ISFT250 semiconductor fuses. This 690V/250A protector reduced equipment downtime by 68% according to plant maintenance logs.
Designed for Modern Power Challenges
The ISFT250’s 100kA breaking capacity handles extreme short circuits that standard fuses can’t contain. Its silver-sand construction enables 3x faster arc extinction compared to conventional ceramic fuses (Schneider lab tests, 2022).
‘It survived our 50,000A simulated fault test when 5 rival products failed’

Real-World Implementation Cases
- Beijing Data Center: Protected 12MW UPS systems from harmonic-induced faults
- Shenzhen Metro: 0 power supply interruptions since 2020 installation
- Jiangsu Solar Farm: Withstood 9 lightning strikes in monsoon season
Schneider’s proprietary thermal modeling ensures stable operation from -40°C to 80°C, crucial for outdoor applications. Maintenance teams appreciate the visual fault indicators that reduced troubleshooting time by 41% (field survey data).
Future-Ready Protection
As factories adopt more IoT devices and variable frequency drives, the ISFT250’s di/dt protection becomes vital. Its 5-year warranty and global certifications (IEC 60269, UL 248) make it the safe choice for upgrading legacy systems.
