£102.45
The Mersen L081798, also identified as 55GD55V25, is a high-performance medium-voltage cylindrical fuse-link designed to provide dependable overcurrent and short-circuit protection for electrical distribution systems. Rated at 25 A and 5.5 kV AC, it is suitable for protecting industrial switchgear, public lighting installations and medium-voltage power distribution equipment.
As part of Mersen's trusted range of medium-voltage fuse-links, the L081798 delivers rapid fault interruption with current-limiting performance, helping minimise thermal and mechanical stress on transformers, cables and associated electrical equipment. Its proven design supports improved system reliability and reduced maintenance requirements.
Manufactured with a cylindrical body measuring approximately 55 × 259 mm, this fuse-link is intended for installation in compatible medium-voltage fuse holders and protection assemblies. Proper fuse selection and coordination are essential for safe operation and optimum protection performance.
Medium-voltage fuse-links are designed to interrupt excessive fault currents before they can damage transformers, switchgear and other valuable electrical assets. Their current-limiting characteristics reduce peak fault current and minimise thermal stress throughout the protected installation.
The Mersen L081798 should only be installed within compatible fuse holders and selected according to the voltage, current and fault level of the electrical system. Installation should always be completed by suitably qualified personnel.
