European Series Cartridge Style Fuses
The Ferraz Cartidge style semiconductor fuses offer precise and efficient protection of semiconductors where small current ratings are required. Most styles are available with a visual trip indicator which is an integral part of the fuse design. All sizes and styles have corresponding clips, holders, and/or isolators for ease in mounting and convenient fuse replacement. Most holders/isolators can be equipped with a blown fuse microswitch activated by the trip indicator for remote signaling. All these features make the Ferraz cartridge style fuses a favorable solution for low current semiconductor applications
