Description
H105F Fast Fuse
1. Purpose and Use
This series of fuses are suitable for rated DC (AC) 1500V (1A–6A) line protection. They serve as comprehensive protection for instrument power lines and wiring harnesses. Features include strong current limiting capabilities, high breaking capacity, fast short-circuit breaking speed, and resistance to temperature, mechanical and current shocks, and chemical load.
Breaking Capacity: AC (50KA), DC (20KA)
2. Normal Working Conditions
Ambient Temperature: -40℃ to +125℃
3. Use Category
“gR” indicates a fast fuse for full-range protection.
4. Structural Features
The fuse body is made of high-temperature-resistant materials with high flame retardancy. The fuse element is made from 99.99% pure silver, encapsulated inside the tube filled with high-purity quartz sand for arc extinguishing. The terminals are silver-plated, and spot welding ensures strong connection and safety during short-circuit faults. The tube is melamine-based.
