Why Choose the Mersen FR14GG50V50 Cylindrical gG Fuse?

The Mersen FR14GG50V50 is a high-performance gG cylindrical fuse-link designed to provide dependable full-range protection for industrial electrical distribution circuits. Rated at 50 A and 500 V AC, this 14 x 51 mm IEC fuse protects cables, motors, switchgear and low voltage networks against overload and short-circuit currents.

Part of the Mersen range of 14 x 51 mm gG ferrule fuse-links, the FR14GG50V50 combines a robust ceramic body with silver-plated contacts for reliable conductivity, thermal stability and long service life. Its gG operating characteristic provides protection across the complete current range, making it suitable for general-purpose industrial circuit protection.

With a high 120 kA AC breaking capacity and a 250 V DC rating, this fuse is suitable for installations with substantial prospective fault currents. Its standard cylindrical format enables straightforward installation in compatible fuse holders used throughout industrial control panels, distribution boards and OEM machinery.
