The capacitors (unless they are internally fused) in NEPSI''s Metal-Enclosed Power Capacitor Banks are individually fused to protect against case rupture and to provide capacitor isolation due to dielectric and non-dielectric capacitor faults.
This occurs due to the fact that I2t withstand goes down exponentially with fuse link rating rather than linearly. Consequently, the 50 kVar capacitor fusing recommendations only cover those units with voltages up to 9960 V. ** Indicates 2 fuses in parallel. 2 atalog Data CA132047EN Effective November 2015 NXC full-range current-limiting

related to the starting of the motor defined in IEC 60644. The capacitor bank protection fuse-links are described in IEC 60549 (High-voltage fuses for the external protection of shunt capacitors) . Also in this case the fuse should meet the requirements described in the general standard IEC 6028
The fuse, by its design, avoids absorbing all of the available energy on the series group. This fuse is used for capacitor banks with a large number of parallel capacitors. It can be used on applications with essentially infinite parallel stored energy, as long as sufficient back voltage can be developed to force the current to extinguish.
An outdoor capacitor fuse is designed for fusing individual capacitor units in standard outdoor equipment, specifically for voltage classes of 2.8, 5.5, 8.3, 15.5 and 23 kV, and currents of 8 kV, 15/20 kV and 25 kV, 100 A. It also has a high-energy capability for use in outdoor capacitor banks with many parallel capacitor units, with voltage classes of 5.5-18.2 kV and currents of 15-43 A.
Most capacitor fuses have a maximum power frequency fault current that they can interrupt. These currents may be different for inductive and capacitively limited faults. For ungrounded or multi-series group banks, the faults are capacitive limited.
For high voltage capacitor fuses, this is generally defined as 8.3, 15.5 or 23 kV, the distribution system maximum voltages. Other voltage ratings may be available for special applications. When a capacitor fails, the energy stored in its series group of capacitors is available to dump into the combination of the failed capacitor and fuse.
Eaton's Cooper PowerE series bus-mounted expulsion-type capacitor fuse provides highly reliable, economical protection for capacitor banks where medium-energy-interrupting ability is required. See Table 1 for electrical ratings. The fuse tube is constructed of bone-grade fibre overwrapped with epoxy-bonded filament-wound fiberglass.
