Why Choose the Mersen FR8GG40V10I Cylindrical Fuse Link?
The Mersen FR8GG40V10I 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 10 A and 400 V AC, it is suitable for protecting cables, electrical distribution circuits, motors and industrial equipment.
As a gG utilisation category fuse, the FR8GG40V10I can protect circuits across its full operating range, responding to sustained overloads as well as high short-circuit currents. Its current-limiting performance helps reduce the thermal and mechanical stress placed on conductors, switchgear and downstream electrical equipment during fault conditions.
This version includes an integrated visual fuse-operation indicator, allowing maintenance engineers to identify an operated fuse more quickly during inspection. Its durable ceramic body, silver-plated contacts and compact dimensions make it a reliable solution for industrial control panels, switchboards and OEM electrical assemblies.
