ABB High Voltage Fuses - CIL Range, Capacitor Fuses 5.5kV - 23kV

ABB High Voltage Fuses

ABB CIL high voltage fuses are a full range, current limiting type capacitor fuse designed for indoor applications. The primary application for ABB CIL fuses is individual capacitor unit fusing for metal-enclosed high voltage equipment.

ABB CIL Indoor Current Limiting Capacitor Fuses for Use in Metal Clad Enclosed High Voltage Electrical Equipment
ABB CIL HV fuse links are used only for fusing individual single phase capacitor cans - therefore ABB CIL fuse voltage rating can be determined from the voltage rating of the capacitor unit. ABB CIL high voltage fuse links should never be installed above their rated voltage. CIL fuse links should be applied only where there are 2 or more high voltage capacitors in parallel per group and where low inductively limited faults can flow.

General Description ABB CIL Capacitor Fuses
ABB CIL High Voltage Fuse is a full range current limiting capacitor fuse designed for indoor use only. CIL fuse links are available in voltage classes of 5.5 kV, 8.3 kV, 15.5 kV and 23kV. The primary application of these fuses is individual capacitor unit fusing for metal enclosed HV equipments. The CIL fuse is current limiting, indicating and disconnecting - ABB CIL current limiting capacitor fuse is a 2 part design :

  • High current section interrupts high 60 Hz fault currents and/or high frequency discharge current from parrallel capacitors
  • Low voltage section consists of a standard NEMA type K fuse link mounted in a fiber tube. The low current section interrupts fault current association with progressive failure of the capacitor unit dielectric, or 60Hz fault current limited by the circuit impedance to low values.


This type of design reduces fuse replacement cost to the price of a NEMA type K fuse link when low current interruption occurs. The CIL capacitor fuse must be used with an ejector spring - this spring ejects the fuse link’s leader giving a position indication of a blown high voltage fuse.

Capacitor Fuse Application
Voltage : The CIL fuse is used only for fusing individual single phase capacitor cans. Therefore, the CIL fuse voltage rating can be determined from the voltage rating of the capacitor unit. Do not apply CIL fuses above their rated voltage.

Energy: The CIL fuse is generally used on those capacitor banks where
parallel energy is more than 20 kilo-joules or 6000 kVAR.

ABB CIL capacitor fuses are to be applied only where there are 2 or more high voltage capacitors in parallel per group and where low inductively limited faults can flow.
