Mersen Extend Protistor® gR-class Semiconductor Fuse Range
Protistor® is the product brand name of the series of fuses designed for protecting the power semiconductor fuses against faults especially large short-circuit currents.
The 14x51mm and 22x58mm cylindrical fuses are part of Protistor® portfolio. Mersen has simplified the offer with a unique type of gR-class fuses and extended the possibility of ratings with a 63A model for 14x51 dimensions and 125A and 135A for 22x58 dimensions.
Design has been streamlined with a new aspect regarding only the end ferrules. Dimensions and technical characteristics remain the same.
These fuses are RoHS compliant and fully certified for an international acceptance: IEC 60269-4, UL Recognized, UL 248-13, CCC GB 1539.4. The 14x51 and 22x58 Protistor® fuses are 690V rated as per IEC and 700V rated as per UL. Current rating lies between 1A and 63A for 14x51mm models and between 12A and 135A for 22x58mm models.
Both ranges encompass models with or without blown fuse indicator. These ranges join the existing 10x38mm gR-class fuses range (from 1A to 32A) to build a consistent IEC Cylindrical Power Semiconductor Fuses offering.
