Why Choose the Mersen FR8GG40V0.5 Cylindrical Fuse-Link?

The Mersen FR8GG40V0.5 is a compact 8 × 32 mm gG cylindrical fuse-link designed to provide dependable full-range protection for cables, conductors and low-voltage electrical equipment. Its gG operating characteristic enables the fuse-link to protect against both sustained overloads and high short-circuit currents.

As part of the established Mersen FR8 gG ferrule fuse-link range, the FR8GG40V0.5 is engineered for reliable performance in electrical distribution circuits and industrial applications. Its current-limiting operation helps reduce the thermal and mechanical stress imposed on wiring, switchgear and connected equipment during electrical faults.

With a rated current of 0.5 A, an IEC rated voltage of 400 V AC and a compact 8 × 32 mm format, the FR8GG40V0.5 is particularly suitable for low-current control, instrumentation and auxiliary circuits where space-saving protection is required.

Key Advantages

  • Full-range gG protection against overloads and short circuits.
  • 0.5 A rated current for low-current electrical applications.
  • 400 V AC IEC rated voltage.
  • 20 kA breaking capacity for dependable fault interruption.
  • Current-limiting operation helps reduce damaging fault energy.
  • Compact 8 × 32 mm format supports space-conscious panel designs.

Key Features

  • Mersen FR8 gG ferrule fuse-link series.
  • 0.5 A rated current.
  • 400 V AC rated voltage.
  • 8 × 32 mm cylindrical fuse format.
  • gG full-range protection characteristic.
  • High current-limiting performance.
  • Durable ceramic fuse body.
  • Silver-plated electrical contacts.

Reliable Protection for Low-Current Electrical Circuits

The Mersen FR8GG40V0.5 provides full-range protection by responding to prolonged overloads and severe short-circuit conditions. Its current-limiting action reduces the amount of fault energy passing through the circuit, helping protect wiring, terminals and connected electrical devices.

Its low 0.5 A rating makes it suitable for sensitive control and auxiliary circuits, while its compact cylindrical design allows straightforward installation in compatible fuse holders within control panels, machinery and electrical distribution equipment.

Typical Applications

  • Industrial control circuits.
  • Instrumentation and monitoring equipment.
  • Auxiliary electrical circuits.
  • Control panels and switchboards.
  • OEM machinery and automation equipment.
  • Low-voltage cable and conductor protection.
