HHD-B (Fuse-Links acc. DIN standard)

A dassical standard back-up fuse for transformer protection, this type series meets the special requirements set for the area of application. As a back-up fuse, it interrupts currents from 3 to 4 times the rated current all the way to the rated breaking current,making short-circuit protection its main area of application. HHD-B fuses are available for rated voltage ranges of 3/72 kV, 6/12 kV,10/17.5 kv, 10/24 kV and 20/36 kV and also cover rated voltages of 17, 38.5 and 40.5 kV.
HHD-B fuses are available for rated voltage ranges of 3/7.2 kV 

3/7.2 kV " e " = 192 mm
3/7.2 kV " e " = 292 mm
3/7.2 kV " e " = 442 mm
HHD-B fuses are available for rated voltage ranges of  6/12 kV
 
6/12 kV " e " = 192 mm
6/12 kV " e " = 292 mm
6/12 kV " e " = 442 mm
6/12 kV " e " = 537 mm
HHD-B fuses are available for rated voltage ranges of 10/24 kV

10/24 kV " e " = 292 mm
10/24 kV " e " = 442 mm
10/24 kV " e " = 537 mm
HHD-B fuses are available for rated voltage ranges of 20/36 kV
 
20/36 kV " e " = 537 mm
