IEC 60364-4-43 provides requirements for:

– protection of live conductors, PEN conductors, PEM conductors, and PEL conductors against the harmful effects caused by overcurrent,
– coordination of measures for protection against overcurrent.

The requirements of IEC 60364-4-43 do not take into account external influences. Protection of conductors according to IEC 60364-4-43 does not necessarily protect the equipment connected to the conductors. Flexible cables connecting equipment by plugs and socket-outlet to fixed installations are not part of this standard and for this reason, are not necessarily protected against the harmful effects caused by overcurrent.

The text of IEC 60364-4-43 has been approved in Europe as HD 60364-4-43:2023 without any changes.
