Why Choose the Mersen FR14GG69V20 Cylindrical gG Fuse?

The Mersen FR14GG69V20 is a dependable gG cylindrical fuse-link designed to provide full-range protection for industrial electrical distribution circuits. Rated at 20 A and 690 V AC, this 14 x 51 mm IEC fuse protects cables, switchgear, motors and low voltage networks against damaging overload and short-circuit currents.

Part of the Mersen range of 14 x 51 mm gG ferrule fuse-links, the FR14GG69V20 combines a robust ceramic body with silver-plated contacts for reliable conductivity, thermal stability and long service life. Its gG operating characteristic provides protection throughout the complete current range, making it suitable for general-purpose industrial circuit protection.

With a high 120 kA AC breaking capacity, the FR14GG69V20 can safely interrupt substantial prospective fault currents. Its compact cylindrical format allows straightforward installation in compatible fuse holders used throughout industrial control panels, distribution systems and OEM machinery.

Key Advantages

  • Full-range gG protection against overloads and short circuits.
  • 20 A rated current for industrial electrical circuits.
  • 690 V AC IEC voltage rating.
  • High 120 kA AC breaking capacity.
  • Current-limiting performance helps reduce stress on connected equipment.
  • Ceramic construction with silver-plated contacts for dependable operation.

Key Features

  • Mersen FR14 gG cylindrical fuse range.
  • 14 x 51 mm cylindrical fuse-link.
  • 20 A rated current.
  • 690 V AC rated voltage.
  • gG full-range operating characteristic.
  • 120 kA AC breaking capacity.
  • High-strength ceramic insulating body.
  • Silver-plated ferrule contacts.
  • IEC cylindrical fuse-link design.
  • Suitable for compatible 14 x 51 mm fuse holders.

Reliable Full-Range Electrical Protection

The Mersen FR14GG69V20 protects electrical conductors and connected equipment by limiting and interrupting unacceptable overcurrents. Its gG operating characteristic responds to both sustained overloads and severe short-circuit faults, helping prevent damage to cables, switchgear and downstream components.

Its current-limiting performance reduces the thermal and mechanical energy passed through the circuit during a fault. This helps improve installation safety, extend equipment service life and reduce disruption within industrial electrical systems.

Typical Applications

  • Industrial electrical distribution panels.
  • Low voltage switchgear assemblies.
  • Motor control centres.
  • Machine control cabinets.
  • Industrial automation systems.
  • Cable, motor and electrical network protection.
