IEC 60931-3 Ed. 1.0 b:1996, Shunt capacitors of the non-self-healing type for AC power systems having a rated voltage up to and including 1000 V - Part 3: Internal fuses

Applies to internal fuses which are designed to isolate faulty capacitor elements or capacitor unit, in order to allow operation of the remaining parts of that capacitor unit and the bank. Such fuses are not a substitute for a switching device such as a circuit-breaker, or for external protection of the capacitor bank. This publication, together with IEC 60871-4 (1996) cancels and replaces IEC 60593 (1977).
