Description
H10F 0.44A-50A 450V-500V Fast-acting fuse
1. Purpose and Use
This series of fuses are suitable for rated DC150V-1000V (440mA-5A), 450V-500V (10A-50A), AC250V-500V line protection. They provide comprehensive protection for instrument power lines and wiring harnesses with strong current limiting capabilities and fast short-circuit breaking speeds. They can withstand temperature shock, mechanical shock, current shock, chemical load, etc. 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 tube is made of high temperature-resistant material with flame retardancy and hardness. The fuse element is made of 99.99% pure silver enclosed within the tube. The tube is filled with chemically treated high-purity quartz sand as the arc extinguishing medium. Silver-plated contact surfaces ensure excellent conductivity and low power loss. Ends are spot-welded to improve short-circuit safety and reliability.
