Why Choose the Mersen X081486 Medium-Voltage Fuse-Link?

The Mersen X081486, also designated 36GD55V12P, is a high-performance medium-voltage cylindrical fuse-link designed to protect transformers, switchgear and electrical distribution equipment against damaging short-circuit currents. Its current-limiting operation helps reduce the thermal and mechanical stresses placed on protected equipment during severe electrical faults.

Manufactured by Mersen, formerly known as Ferraz Shawmut, the X081486 forms part of the established Limitor medium-voltage fuse range. Its robust construction and dependable fault-clearing characteristics make it suitable for industrial, infrastructure and utility applications where reliable circuit protection is essential.

With a rated voltage of 5.5 kV AC, a rated current of 12 A and a nominal 55 × 259 mm cylindrical format, the Mersen X081486 is designed for installation in compatible medium-voltage fuse holders. An integrated striker supports operation with suitable indication, interlocking or switchgear tripping mechanisms.

Key Advantages

  • Dependable medium-voltage short-circuit protection.
  • 5.5 kV AC voltage rating for medium-voltage distribution systems.
  • 12 A rated current for appropriately coordinated electrical equipment.
  • Current-limiting operation helps reduce damaging fault energy.
  • Integrated striker mechanism for compatible indication or tripping systems.
  • Robust cylindrical construction for demanding industrial environments.

Key Features

  • Mersen Limitor medium-voltage fuse-link.
  • Manufacturer part number X081486.
  • Alternative designation 36GD55V12P.
  • Catalogue designation 559P CP GLD 55.259 12.
  • 5.5 kV AC rated voltage.
  • 12 A rated current.
  • GLD fuse characteristic.
  • Nominal 55 × 259 mm cylindrical format.
  • Integrated striker for compatible switchgear operation.
  • Current-limiting technology for rapid fault interruption.

Reliable Protection for Medium-Voltage Equipment

Medium-voltage fuse-links interrupt excessive fault currents before they can cause extensive thermal or mechanical damage to transformers, switchgear, conductors and connected equipment. The fuse element operates rapidly during a short circuit, while the internal arc-control system extinguishes the resulting electrical arc.

The Mersen X081486 provides current-limiting protection that restricts both the peak magnitude and duration of a fault current. This supports improved equipment protection, reduced system damage and dependable operation across industrial and utility power-distribution installations.

Typical Applications

  • Medium-voltage transformer protection.
  • Industrial switchgear and controlgear.
  • Electrical distribution networks.
  • Utility and infrastructure installations.
  • Medium-voltage feeder circuits.
  • Industrial power-distribution equipment.
