Why Choose the Mersen W1003900 BS88 Fuse-Link?
The Mersen W1003900 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 protecting high-current cables, switchgear, distribution boards and electrical infrastructure operating at up to 415 V AC.
This industrial fuse-link uses a robust ceramic body and durable blade terminals to deliver reliable performance in demanding commercial, municipal and industrial environments. Its high fault-interruption capability helps protect electrical equipment by safely disconnecting the circuit when excessive current occurs.
With a rated current of 250 A, the Mersen W1003900 is designed for higher-capacity feeder and distribution circuits. Its general-purpose full-range operating characteristic provides protection against both sustained overloads and high-level short-circuit faults.

Reliable Protection for High-Current Electrical Circuits
BS88 fuse-links protect electrical installations by disconnecting circuits when the current exceeds safe operating limits. During overload or short-circuit conditions, the internal fuse element interrupts the fault before excessive thermal or electrical energy can damage cables, switchgear and connected equipment.
The Mersen W1003900 provides dependable protection for high-current feeder circuits and low voltage distribution systems. Its industrial construction and standardised blade-terminal arrangement make it suitable for installations where effective fault isolation, equipment protection and long-term reliability are essential.
