Why Choose the Mersen M081477 55GD55V100P Medium-Voltage Fuse?
The Mersen M081477, also identified as 55GD55V100P, is a high-performance medium-voltage cylindrical fuse-link designed to protect electrical distribution equipment against damaging overcurrents and short-circuit faults. Rated at 100 A and 5.5 kV AC, it is suitable for demanding industrial, infrastructure and utility protection applications.
Manufactured as part of Mersen's specialist medium-voltage fuse range, the M081477 provides rapid fault interruption and effective current limitation. This helps reduce the thermal and mechanical stresses imposed on transformers, cables, switchgear and other valuable electrical equipment during severe fault conditions.
The fuse is identified by the manufacturer description 559P CP GLD 55.259 100 and features a cylindrical body measuring approximately 55 × 259 mm. The P designation indicates a striker-equipped configuration, enabling mechanical indication or operation of compatible auxiliary devices when the fuse ruptures.

Reliable Protection for Medium-Voltage Equipment
Medium-voltage fuse-links interrupt excessive current before it can cause extensive thermal or mechanical damage within an electrical installation. Their current-limiting action restricts the peak fault current and reduces the energy passed into transformers, switchgear, cables and other protected equipment.
The Mersen M081477 must be installed within a correctly rated and dimensionally compatible fuse holder. Selection should consider the system voltage, normal load current, transformer or equipment characteristics, prospective fault level and coordination with other protective devices.
Typical Applications
- Medium-voltage electrical distribution systems.
- Transformer and feeder protection.
- Industrial switchgear assemblies.
- Utility and infrastructure installations.
- Protection of cables and electrical equipment.
- Replacement fuse-links for compatible Mersen fuse systems.
