BS EN 60143-3:2015

This standard BS EN 60143-3:2015 Series capacitors for power systems is classified in these ICS categories:

• 31.060.70 Power capacitors
• 29.120.50 Fuses and other overcurrent protection devices

This part of IEC 60143 applies to internal fuses designed to isolate faulty capacitor elements, to allow operation of the remaining parts of that capacitor unit and the bank in which the capacitor unit is connected. Such fuses are not a substitute for a switching device such as a circuit-breaker, or for external protection of the capacitor bank, or any part thereof.

The object of this part of IEC 60143 is:

• to formulate requirements regarding performance and testing;

• to provide a guide for coordination of fuse and bank protection.
