Why Choose the Mersen FR8GG40V8I Cylindrical Fuse Link?
The Mersen FR8GG40V8I is a compact 8 × 32 mm cylindrical gG fuse link designed to provide dependable full-range protection against overloads and short circuits in low-voltage electrical installations. Rated at 8 A and 400 V AC, it is suitable for protecting cables, motors, distribution circuits and industrial electrical equipment.
As a gG utilisation category fuse, the FR8GG40V8I protects circuits across its complete operating range. It limits and interrupts unacceptable overload and short-circuit currents, helping protect conductors, switchgear and connected equipment from damaging thermal and dynamic effects.
This version features an integrated visual fuse-operation indicator, enabling maintenance engineers to identify an operated fuse quickly during inspection. Its ceramic body, silver-plated contacts and compact cylindrical construction provide reliable performance in industrial control panels, switchboards and OEM electrical assemblies.
