Why Choose the Mersen B081789 High-Voltage Fuse Link?
The Mersen B081789, also identified as 36GD32V40P, is a high-voltage cylindrical fuse link with integrated striker designed to provide dependable protection for medium and high-voltage electrical distribution systems. Rated at 40 A and 3.2 kV AC, it is engineered for transformer protection, switchgear and industrial power distribution applications.
Manufactured by Mersen (formerly Ferraz Shawmut), the B081789 features a compact 36 × 190 mm cylindrical format with an integrated striker mechanism. The striker provides mechanical indication and can operate auxiliary contacts when used with compatible fuse holders, enabling faster fault identification and improved maintenance efficiency.
The manufacturer description 329P CP GLD 36.190 40 identifies the fuse's voltage class, GLD operating characteristic, physical dimensions and current rating. Designed for demanding industrial environments, the B081789 delivers reliable current-limiting protection while helping minimise damage to transformers, cables and switchgear during fault conditions.
