Fuses For Semiconductor Protection North AmericanEuropean Standard TYPE SQB Sizes 1, 2 AND 3 SIBA square body fuses type SQB are available in 3 different body sizes. Each size is available in various mounting styles for global applications. Variety in body sizes, mounting styleamp ratings allow the greatest flexibility in equipment design.SIBA SQB fuses provide superior engineering for the protection of today’s power semiconductors. The silicated process together with special shapeformof the pure silver melting elements give excellent results of low I2t-valueshigh interrupting ratings. And they are the most reliable under high cycling load conditions. All fuses can be fitted with microswitches.Standards: DIN 43653, DIN VDE 0636-40IEC 60269-4UL 248-13Class: aRVoltage ratings: AC700 V /AC1300 VCurrent ratings: 50 up to 1600 ASizes: 1, 23High interrupting rating 200 kAVery low I2t-valuesVoltage ratings AC 690/700 VAC 1250/1300 VSuitable for North AmericanEuropean standardReliable also at high cyclic loadingFuse basesAccessories are availableDownload PDF Catalog for more Information －－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－Fuses For Semiconductor Protection European Standard Class gR This line of gRL class fuses offers superior combination of two fuses into one.Type gRL fuses provide protection to power electronic equipmentcables with low power losseslow I2t-values simultaneously.Fuse type gRL offers:Semiconductor protection against short circuit faults via their Ultra Rapid “gR” characteristic.Cable protection against overload via their “gG” characteristic.High current limitationLow power lossesSemiconductor protection against short circuit faultsCable protection against overload currentLow I2t-valuesHigh interrupting rating up to 200 kACompliance with the following standards: IEC 60269-1 / -2-1-4 • DINClass gRL follows the requirements of the new standardized class gSDownload PDF Catalog for more Information －－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－Fuses For Semiconductor Protection Cylindrical Fuses – European Standard SIBA cylindrical ultra-rapid fuses are available in 6 different sizes.
