Why Choose the Mersen J222165 DIII gG/Flink Fuse Link?

The Mersen J222165 is a fast-acting DIN D screw fuse link designed to protect low-voltage electrical equipment against potentially damaging overcurrents and short circuits. Identified by the catalogue number DIIIFK50V50, it provides a 50 A rated current and is suitable for circuits operating at up to 500 V AC or 500 V DC.

As part of the Mersen D fuse-links Flink series, the J222165 provides faster operation than a conventional D gG fuse link. This rapid fault-clearing performance helps limit the thermal and mechanical energy passed to cables, conductors and connected electrical equipment during an overcurrent condition.

The fuse is manufactured in the established DIII screw-fuse format used throughout industrial and commercial low-voltage distribution systems. Its durable insulated body, nickel-plated copper-alloy contacts and clear visual operating indicator support reliable performance and straightforward maintenance in demanding electrical installations.

Key Advantages

  • Fast-acting gG/Flink fuse link for dependable equipment protection.
  • 50 A rated current for low-voltage distribution circuits.
  • Suitable for systems operating at up to 500 V AC or 500 V DC.
  • Current-limiting operation helps reduce damaging fault energy.
  • Standard DIII DIN screw-fuse format for established fuse systems.
  • White colour coding enables quick identification of the current rating.

Key Features

  • Mersen D fuse-links Flink series.
  • Catalogue number: DIIIFK50V50.
  • 50 A nominal current rating.
  • 500 V AC and 500 V DC rated voltage.

  • Insulated body with high mechanical and thermal resistance.
  • Coloured operating indicator positioned on the top contact.

Fast Protection for Low-Voltage Equipment

DIN D fuse links protect electrical installations by interrupting excessive current before it can damage cables, components or connected equipment. The fast operating performance of the Mersen J222165 allows short circuits and overcurrents to be cleared rapidly, reducing the energy that passes through the protected circuit.

The D screw-fuse system remains widely installed in low-voltage distribution equipment because of its durable construction and straightforward replacement process. The J222165 is particularly suited to existing installations requiring a 50 A DIII Flink fuse link with both AC and DC voltage capability.

Typical Applications

  • Low-voltage distribution boards.
  • Industrial electrical control panels.
  • Commercial electrical installations.
  • Machinery and production equipment.
  • Cable and conductor protection.
  • DIN D screw-fuse assemblies.
