Why the FERRAZ C300083 6.9URD33TTF1100 Stands Out in Circuit Protection
In the world of industrial power systems, reliability isn’t just a buzzword—it’s a necessity. The FERRAZ C300083 6.9URD33TTF1100 fuse has become a go-to solution for engineers seeking robust overcurrent protection. Designed for high-voltage applications up to 690V AC and rated for 1100A, this fuse combines precision engineering with FERRAZ’s 90+ years of expertise in circuit protection.
Real-World Application: Solar Farm Power Distribution
A recent project in Spain’s 50MW solar farm highlights its effectiveness. The facility’s inverters, operating at 600V DC, faced frequent voltage surges due to grid fluctuations. After installing the 6.9URD33TTF1100 fuses, downtime caused by overloads dropped by 78% over 12 months. “These fuses reacted 30% faster than our previous solution during fault conditions,” noted the site’s lead engineer.
Built for Extreme Conditions
- Operating temperature range: -50°C to +125°C
- 100kA breaking capacity at 690V
- Compact 6.9mm x 33mm form factor
Field tests in offshore wind turbines (where saltwater corrosion is a constant threat) showed zero performance degradation after 5,000 operational hours—a critical factor for maintenance teams.
Data-Driven Reliability
Third-party lab tests reveal:
| Parameter | Result |
|---|---|
| Pre-arcing time at 2x In | ≤10ms |
| Total clearing energy | 15kJ max |
These metrics explain why global manufacturers trust this fuse for mission-critical equipment like EV charging stations and CNC machining centers.
