Reliable BS88 gG Type F2 415VAC 40A BES Offset Blade Fuse-Link for industrial and commercial electrical systems, providing high breaking capacity and secure installation.
£10.16
The Mersen BES42V40 is a compact BS88 offset blade fuse link designed to provide dependable overload and short-circuit protection in industrial and commercial electrical systems. Manufactured by Mersen, this gG general-purpose fuse is suitable for distribution boards, switchgear, control panels and OEM equipment requiring reliable low-voltage circuit protection.
Its full-range gG operating characteristic protects cables, conductors and general electrical equipment against sustained overload currents and high-level short circuits. During a fault, the fuse rapidly limits and interrupts excessive current, helping to reduce thermal and mechanical stress on switchgear, wiring and connected equipment.
With a 40 A rated current and a nominal voltage class of 415 V AC, the Mersen BES42V40 is suitable for compatible BS88 fuse holders, fuse switches and distribution assemblies. Its offset blade construction provides a secure electrical connection and enables straightforward replacement during planned maintenance.
gG fuse links provide full-range protection for cables and general electrical equipment. Their operating characteristics allow normal circuit currents to pass while interrupting sustained overloads and short-circuit currents before significant damage can occur.
The Mersen BES42V40 combines a practical 40 A rating with an offset blade design, making it suitable for industrial distribution, control and machinery circuits where reliable fault interruption and convenient replacement are required.
