Brand History: Ferraz Shawmut

Ferraz Shawmut is the former name of Mersen's electrical protection division. The Ferraz Shawmut brand was established through the merger of Ferraz (France) and Shawmut (United States), both long-standing manufacturers of industrial fuses. Mersen acquired and rebranded the Ferraz Shawmut product line. Legacy Ferraz Shawmut part numbers and catalog designations remain valid under the Mersen name.
