The Mersen product range includes an extensive range of innovative Modulostar fuse holders. The modular fuse holders are finger-safe according to IEC and comply with protection class IP20 even during fuse replacement. Modulostar fuse holders are available in 1-, 2-, 3- or 4-pole versions. Mersen offers variants with or without optical fuse monitoring, in UL and IEC versions. With a mounting kit, single-pole units can be combined to form multi-pole units. In sizes 14 or 22, microswitches can be used as an option for remote indication. These are supplied with the fuse holder or can be retrofitted as an accessory. Modulostar products offer optimal mechanical and thermal resistance.
