Why Choose the Mersen FR8GG40V25I Cylindrical Fuse Link?

The Mersen FR8GG40V25I is a compact gG cylindrical fuse link designed to provide full-range protection against overload and short-circuit currents in low-voltage electrical distribution systems. Part of the established Mersen 8 × 32 mm IEC ferrule fuse range, it is suitable for protecting cables, conductors, industrial equipment and general-purpose electrical circuits.

Its gG operating characteristic enables the fuse to protect across the complete overcurrent range, from sustained overloads through to severe short-circuit faults. The ceramic body and silver-plated contacts provide dependable thermal performance, effective current limitation and reliable electrical conductivity in industrial installations.

With a rated current of 25 A, a rated voltage of 400 V AC and an integrated visual indicator, the FR8GG40V25I is well suited to control panels, distribution equipment and machinery where clear identification of an operated fuse is beneficial.

Key Advantages

  • Full-range gG protection against overload and short-circuit currents.
  • 25 A current rating for low-voltage distribution circuits.
  • 400 V AC rated voltage for industrial electrical systems.
  • Integrated visual fuse-operation indicator.
  • Current-limiting performance helps reduce stress on downstream equipment.
  • Compact 8 × 32 mm IEC cylindrical format.

Key Features

  • Mersen 8 × 32 mm gG cylindrical fuse-link series.
  • 25 A rated current.
  • 400 V AC rated voltage.
  • Full-range gG utilisation category.
  • Integrated visual indicator for easier fault identification.
  • Durable ceramic fuse body.
  • Silver-plated contacts for reliable conductivity.
  • Suitable for cable, equipment and low-voltage network protection.

Reliable Protection for Low-Voltage Electrical Circuits

The Mersen FR8GG40V25I protects electrical installations by interrupting excessive currents before they can cause cable overheating, insulation damage or equipment failure. Its gG characteristic provides protection against both overload and short-circuit conditions, making it suitable for general-purpose industrial circuit protection.

The integrated visual indicator provides a clear means of identifying when the fuse has operated, helping maintenance personnel locate faults and replace affected fuse links more efficiently. The fuse should be installed in a compatible 8 × 32 mm fuse holder rated for the relevant circuit voltage and current.

Typical Applications

  • Industrial electrical control panels.
  • Low-voltage distribution circuits.
  • Cable and conductor protection.
  • Machinery and automation equipment.
  • Switchgear and fuse assemblies.
  • OEM electrical systems.
