Medium Voltage Fuses for Capacitors Back-up North American Style. 

The new range of SIBA HV fuse-links HHC provides maximum protection in capacitor applications. The fuses are designed to be mounted directly to the capacitor bushings in individual fusing applications, indoor and outdoor. The fuses are available in a variety of different thread sizes such as 1/2 inch, M12, M16. An additional L-shape range for bus-mounting also provides a 50 N striker for both visualizing the fuse operation and triggering the SIBA Micro-Switch-Fitting 3100210. This Micro-Switch-Fitting produces an electrical signal for each operated fuse.

Application

Rated voltage

In contrast to a standard HV fuse-link, all HHC types already respect the higher voltage level necessary for a proper capacitor protection. Therefore, the rated voltage of a HHC fuse-link can be the same as the application voltage, also the case of floating-wye connections. For example an 8.3 kV fuse can be placed in a 7.96 kV floating-wye system.

 

Rated current

To respect the influences and tolerances mentioned in

IEEE 18-1992, like:

  • Tolerance of capacitor rating S = 1,15xS
  • Tolerance of the application voltage U = 1.1xU
  • Harmonic influences
  • Inrush currents

The rated current of the selected SIBA HHC fuse-link shall be min. 2 times the operation current of the application
