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

SIBA-DC-Fuses are offered in clip-mounted and bolt-design. The fuses are used for applications in traction-, battery, and railwaymain- 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, classes or L/R’s.
