Why Choose the Mersen FR14GG69V1 Cylindrical Fuse-Link?
The Mersen FR14GG69V1 is a reliable gG cylindrical fuse-link designed to provide full-range protection against overloads and short circuits in electrical distribution circuits, low-voltage networks and industrial equipment. Part of Mersen's established range of IEC cylindrical fuses, it combines compact dimensions with dependable current-limiting performance.
Its gG operating characteristic enables the fuse-link to protect cables, conductors, motors and electrical equipment across the complete overcurrent range. During a fault, the fuse rapidly limits and interrupts excessive current, helping reduce thermal and mechanical stress on downstream components.
Rated at 1 A, 690 V AC and 250 V DC, the FR14GG69V1 is supplied in a standard 14 × 51 mm cylindrical format. Its ceramic body, silver-plated copper ferrules and high breaking capacity make it suitable for demanding industrial and commercial installations.
