Mersen D081814 36GD32V50 gLD medium-voltage cylindrical fuse-link rated at 50 A and 3.2 kV AC, with a 36 x 190 mm format for transformer, switchgear and distribution protection.
£96.66
The Mersen D081814, also identified as 36GD32V50, is a dependable medium-voltage cylindrical fuse-link designed to protect transformers, switchgear and electrical distribution equipment against damaging short-circuit currents. Rated at 50 A and 3.2 kV AC, it provides effective current-limiting protection for demanding industrial, utility and infrastructure applications.
Featuring a gLD operating characteristic, the D081814 responds rapidly when a serious electrical fault occurs. Its current-limiting action helps reduce the peak short-circuit current and the amount of energy transferred into downstream equipment, limiting thermal and mechanical stress on transformers, cables and switchgear components.
The fuse has a robust 36 × 190 mm cylindrical construction designed for installation in a compatible medium-voltage fuse carrier or switch-fuse assembly. Its reliable electrical performance makes it suitable for new installations, planned maintenance and replacement applications where system continuity and effective fault protection are essential.
Medium-voltage fuse-links interrupt dangerous fault currents before they can cause extensive damage to electrical equipment. The Mersen D081814 limits the peak short-circuit current and reduces the energy passed through the circuit, helping protect transformers, switchgear, cables and connected distribution components.
Correct fuse selection should consider the system voltage, continuous operating current, prospective short-circuit current, fuse dimensions and coordination with other protective devices. The fuse must be installed in a compatible carrier with suitable voltage, current and dimensional ratings.
