Why Choose the Mersen B081490 High-Voltage Fuse Link?
The Mersen B081490, also identified as 55GD55V100, is a robust high-voltage cylindrical fuse link designed to protect electrical distribution equipment against damaging overcurrents and short circuits. Rated at 100 A and 5.5 kV AC, it is suitable for demanding industrial and infrastructure applications requiring reliable high-voltage circuit protection.
Featuring a substantial 55 × 259 mm cylindrical format, the B081490 is intended for installation in a correctly rated high-voltage fuse holder or switchgear assembly. Its engineered fuse element interrupts excessive current when an electrical fault occurs, helping limit thermal and mechanical stress on transformers, cables, switchgear and connected equipment.
The manufacturer description 5500 CP GLD 55.259 100 identifies the fuse's voltage class, GLD operating characteristic, physical dimensions and current rating. Manufactured by Mersen, formerly associated with the Ferraz Shawmut brand, the B081490 provides dependable protection for specialised power distribution systems.

Reliable Protection for High-Voltage Electrical Systems
High-voltage electrical installations require correctly coordinated protection to prevent abnormal current from causing serious damage to insulation, conductors and connected equipment. The Mersen B081490 is designed to interrupt unacceptable fault current and isolate the affected circuit before the fault develops into a more extensive equipment failure.
Its combination of a 100 A current rating, 5.5 kV AC voltage capability and substantial cylindrical construction makes it suitable for specialised industrial power systems. The fuse should always be selected in accordance with the equipment manufacturer's requirements for voltage, current, breaking capacity, operating characteristic and physical dimensions.
