Why Choose the Mersen BES55V20 BS88 Offset Blade Fuse-Link?
The Mersen BES55V20 is a British Standard BS88 gG Type F2 offset blade fuse-link designed to provide dependable general-purpose protection for low-voltage industrial and commercial electrical installations. Rated at 20 A and 550 V AC, it complies with EN 60269-2 Section II and BS88 Part 6, delivering reliable protection against overloads and short circuits.
The BES55V20 is manufactured with plain offset blades for secure installation into compatible BS88 fuse holders, fuse-switch disconnectors or direct busbar-mounted assemblies. Its gG operating characteristic provides full-range protection for cables, switchgear and distribution equipment across a wide range of industrial applications.
Designed with excellent current-limiting characteristics, the fuse helps minimise thermal and mechanical stress during fault conditions while ensuring compliance with recognised British and IEC standards.
