Why Choose the Mersen FR10GG40V20P Cylindrical gG Fuse?

The Mersen FR10GG40V20P is a compact gG cylindrical fuse-link with striker, designed to provide dependable full-range protection for low voltage electrical distribution circuits. Rated at 20 A and 380 V AC, this industrial fuse protects cables, motors, switchgear and connected equipment against overloads and short-circuit currents.

Part of the Mersen range of 10 x 38 mm IEC cylindrical fuse-links, the FR10GG40V20P combines a robust ceramic body with silver-plated copper ferrules for reliable electrical performance. Its gG operating characteristic provides comprehensive protection throughout the complete current range, making it suitable for general industrial circuit protection.

The integrated striker indication system can be used with a compatible fuse holder or auxiliary contact to provide remote fuse operation signalling. With a high 100 kA AC breaking capacity, the FR10GG40V20P can safely interrupt substantial prospective fault currents in industrial installations.

Key Advantages

  • Full-range gG protection against overloads and short circuits.
  • 20 A rated current for industrial electrical circuits.
  • 380 V AC IEC voltage rating.
  • Integrated striker indication system.
  • High 100 kA AC breaking capacity.
  • Compact ceramic construction with silver-plated copper contacts.

Key Features

  • Mersen FR10 gG cylindrical fuse range.
  • 10 x 38 mm cylindrical fuse-link.
  • 20 A rated current.
  • 380 V AC rated voltage.
  • gG full-range operating characteristic.
  • 100 kA AC breaking capacity.
  • Integrated striker for fuse operation indication.
  • Silver-plated copper ferrule terminals.
  • High-strength ceramic insulating body.
  • RoHS-compliant construction.

Reliable Full-Range Circuit Protection

The Mersen FR10GG40V20P protects electrical conductors and equipment by limiting and interrupting unacceptable overload and short-circuit currents. Its current-limiting action helps reduce the thermal and mechanical stress placed on cables, switchgear and connected components during electrical faults.

The built-in striker provides clear mechanical indication when the fuse has operated and can activate a compatible auxiliary contact for remote status monitoring or interlocking. This functionality makes the fuse particularly useful in industrial control panels where rapid fault identification can help minimise downtime.

Typical Applications

  • Industrial electrical distribution circuits.
  • Machine control panels.
  • Motor and cable protection circuits.
  • Low voltage switchgear assemblies.
  • Industrial automation equipment.
  • OEM machinery and production systems.
