Mersen offers tried, proven and approved fuses and fusegear complying with the Bristish Standard BS88-2

Mersen is the leader in the French standard cylindrical fuses and fusegear for the protection of low voltage. The brand offers premium components providing space savings combined with low power losses.

The D fuse-system is the first generation of screw fuse-system in the German DIN standard.

Mersen cable protectors are special purpose limiters which are crimped or bolted to cables to clear and isolate faults quickly, increasing the reliability of service entrance and distribution runs.

Mersen's One-Time general purpose fuses provide low cost protection for feeder and branch-circuits serving lighting, heating, and other non-motor loads. Class K5 fuses will safely interrupt available short-circuit currents up to 50,000 amperes in all ratings up to 600 VAC.

Mersen R-Rated fuses are current-limiting, high interrupting rating fuses intended for the short circuit protection of medium voltage motors and motor controllers.

Mersen fuses for the protection of transformers and distribution lines deliver overload and short circuit protection, and are designed to withstand the transformer magnetizing inrush current.
