Who We Are
Mersen Express is an independent distributor and stockist of Mersen electrical protection products. We supply the complete Mersen range — low-voltage and medium-voltage fuses, high-speed semiconductor fuses, fuse holders and fuse systems, Surge-Trap® surge protective devices, fuse switch disconnectors and power distribution blocks.
Why Mersen
Mersen — formerly Ferraz Shawmut — has been a global expert in electrical power protection for over 130 years. Its devices are specified in industrial control panels, power electronics, renewable energy, data centres and rail systems worldwide. Fuses marked Ferraz Shawmut and Mersen with the same part number are the same product, so we can supply current equivalents for legacy references.
