Why Choose the Mersen BTMF69V315 BS88 gG Fuse Link?
The Mersen BTMF69V315 is a heavy-duty BS88 central bolted tag fuse link designed to provide dependable overload and short-circuit protection in industrial power distribution systems. Manufactured by Mersen, this gG general-purpose fuse is suitable for switchgear, fuse switch disconnectors, distribution panels and OEM electrical equipment requiring reliable high-current protection.
Its full-range gG operating characteristic protects cables, conductors and general electrical equipment against sustained overloads and severe short-circuit faults. During a fault, the fuse rapidly limits and interrupts excessive current, helping to reduce thermal and mechanical stress on busbars, switchgear and connected equipment.
With a 315 A rated current, 690 V AC and 460 V DC voltage ratings, the Mersen BTMF69V315 is suitable for demanding industrial installations. Its central bolted tag construction provides a secure mechanical mounting arrangement and dependable electrical contact in compatible BS88 fuse assemblies.
