Why Choose the Mersen FR14GG69V10 Cylindrical Fuse-Link?

The Mersen FR14GG69V10 is a dependable gG cylindrical fuse-link designed to provide full-range protection against overloads and short circuits in industrial electrical distribution systems. Part of Mersen's established low-voltage IEC fuse range, it combines reliable current-limiting performance with a compact and durable 14 × 51 mm ceramic body.

Its gG operating characteristic makes the FR14GG69V10 suitable for protecting cables, motors, low-voltage networks and connected electrical equipment across the complete overcurrent range. During a fault, the fuse-link rapidly limits and interrupts excessive current, helping reduce thermal and mechanical stress on downstream components.

Rated at 10 A, 690 V AC and 250 V DC, the FR14GG69V10 provides a high 120 kA AC breaking capacity. Its standard cylindrical format allows straightforward installation in compatible fuse holders within switchboards, control panels, machinery and industrial distribution equipment.

Key Advantages

  • Full-range gG protection against overloads and short circuits.
  • 10 A rated current for industrial control and distribution circuits.
  • 690 V AC and 250 V DC ratings provide versatile system compatibility.
  • 120 kA AC breaking capacity for dependable interruption of high fault currents.
  • Current-limiting performance helps reduce equipment and cable damage.
  • Compact 14 × 51 mm design saves space within electrical panels.

Key Features

  • Mersen FR14GG cylindrical fuse-link series.
  • gG full-range fuse characteristic.
  • 10 A rated current.
  • 690 V AC IEC rated voltage.
  • 250 V DC IEC rated voltage.
  • 14 × 51 mm cylindrical fuse size.
  • 120 kA AC breaking capacity.
  • 100 kA DC breaking capacity at 250 V DC.
  • Ceramic insulating body.
  • Silver-plated copper ferrule terminals.

Reliable Full-Range Circuit Protection

The Mersen FR14GG69V10 protects electrical installations by limiting and disconnecting unacceptable overload and short-circuit currents. Its gG classification provides full-range protection, making it suitable for safeguarding conductors, motors and general low-voltage electrical equipment.

During a high-current fault, the fuse-link's current-limiting action reduces the energy passed to downstream components. This helps minimise thermal damage, mechanical stress and disruption within industrial control and power distribution systems.

Typical Applications

  • Industrial electrical distribution systems.
  • Cable and conductor protection.
  • Low-voltage power networks.
  • Motor and machinery circuits.
  • Automation and control panels.
  • Switchboards and OEM electrical equipment.
