Why Choose the Mersen L081614 FR36GB55C20 Medium-Voltage Fuse?

The Mersen L081614, also identified as FR36GB55C20, is a high-performance medium-voltage cylindrical fuse-link engineered to provide dependable protection against overloads and short-circuit faults in electrical distribution systems. Rated at 20 A and 5.5 kV AC, it is specifically designed for public lighting networks, industrial switchgear and medium-voltage power distribution equipment.

Part of Mersen's proven Limitor® medium-voltage fuse range, the L081614 delivers rapid fault interruption with current-limiting performance to reduce thermal and mechanical stress on transformers, cables, switchgear and associated equipment. This helps improve system reliability while minimising downtime following electrical faults.

Manufactured with a cylindrical body measuring approximately 36 × 250 mm, this fuse-link is intended for installation within compatible medium-voltage fuse holders and protection assemblies. Correct fuse coordination ensures optimum protection and dependable long-term operation in demanding industrial environments.
