Mersen D-Fuse Link D III, 63A, Copper, DIIIGG50V63

The Mersen D-Fuse Link D III, 63A is a high-quality DIAZED fuse link designed for cable and line protection in industrial installations. With a rated current of 63A and voltage of 500V AC, it offers reliable overcurrent protection. The fuse features a gG characteristic (general purpose) and a breaking capacity of 50kA, ensuring safety under fault conditions. Its copper, silver-plated contacts provide excellent conductivity, while the ceramic body ensures durability and thermal stability. Compliant with IEC 60269-3 and VDE 0636-301 standards, this fuse link is RoHS compliant and suitable for use in screw-in D-fuse bases.

Advantages

High breaking capacity of 50kA ensures safe interruption of fault currents. Silver-plated copper contacts minimize power dissipation (6.5W) and enhance reliability. Ceramic body withstands high temperatures and provides excellent insulation. gG characteristic offers general-purpose protection for cables and lines.
