£41.28
The Mersen Y1003902 is a high-performance British Standard IEC BS88 industrial fuse-link designed to provide dependable overload and short-circuit protection for low voltage electrical distribution systems. Part of Mersen’s feeder pillar fuse range, it is suitable for street lighting networks, switchgear, distribution boards and industrial power circuits operating at up to 415 V AC.
Also identified by catalogue number BJU42V040SA, this fuse-link features a robust ceramic body and blade terminals with a 92 mm fixing centre. Its industrial construction supports reliable operation in demanding commercial, municipal and infrastructure environments.
With a rated current of 40 A and a general-purpose full-range operating characteristic, the Mersen Y1003902 protects cables and electrical equipment against sustained overloads and short-circuit faults. Its 80 kA breaking capacity enables safe interruption of substantial prospective fault currents.
BS88 fuse-links protect electrical installations by disconnecting circuits when current exceeds safe operating levels. During an overload or short-circuit condition, the fuse element interrupts the fault before excessive heat or electrical energy can damage cables, switchgear or connected equipment.
The Mersen Y1003902 provides dependable full-range protection for feeder and distribution circuits. Its ceramic construction, high breaking capacity and standardised blade-terminal arrangement make it suitable for installations where reliable fault isolation and long-term electrical safety are essential.
