MERSEN FUSE 25500 CP GL 20.340 1 B098464

Why Choose the Mersen B098464 High Voltage Fuse Link?

The Mersen B098464, also identified as 20GL25V1, is a high voltage cylindrical fuse link designed to provide dependable protection for voltage transformers, switchgear and specialised medium-voltage electrical distribution systems. Rated at 1 A and 25.5 kV AC, it delivers reliable overcurrent protection for demanding industrial and utility applications.

Manufactured by Mersen (formerly Ferraz Shawmut), the B098464 features a 20 × 340 mm cylindrical construction. Its precision fuse element rapidly interrupts fault currents, helping protect voltage transformers, measurement equipment and associated switchgear from thermal and mechanical damage during electrical faults.

The manufacturer description 25500 CP GL 20.340 1 identifies the fuse's voltage class, physical dimensions and current rating. Designed for use in compatible high voltage fuse holders, it provides dependable protection in medium-voltage installations where accurate low-current protection is essential.
