Fuses For Semiconductor Protection
North American and European Standard TYPE SQB Sizes 1, 2 AND 3

SIBA square body fuses, types SQB, are available in 3 different body sizes. Each size is available in various mounting styles for global applications. Variety in body sizes, mounting style and amp ratings allow the greatest flexibility in equipment design. SIBA SQB fuses provide superior engineering for the protection of today�s power semiconductors. The silicate process together with special shape and form of the pure silver melting elements give excellent results of low I2t-values and high interrupting ratings. And they are the most reliable under high cycling load conditions. All fuses can be fitted with micro switches.

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 equipment and cables with low power losses and low 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 limitation

  • Low power losses

  • Semiconductor protection against short circuit faults

   
  • Cable protection against overload current

  • Low I2t-values

  • High interrupting rating up to 200 kA

  • Compliance with the following standards: IEC 60269-1 / -2-1 and -4 • DIN

  • Class gRL follows the requirements of the new standardized class gS

Dc-Application / Traction Fuse

SIBA-DC-Fuses are offered in clip-mounted and bolt-design. The fuses are used for applications in traction-, battery, and railway main- circuits. They are largely used for the protection of frequency-inverters. Because the application is possible in a big variety one should contact SIBA to have information regarding the use at different voltage ratings, classess or L/R’s.
