Foreword
The text of document 64/1641/FDIS, future edition 1 of IEC 60364-4-43, prepared by TC 64, Electrical
installations and protection against electric shock, was submitted to the IEC-CENELEC parallel vote.
A draft amendment, prepared by SC 64B, Electrical installations and protection against electric shock –
Protection against thermal effects, of Technical Committee CENELEC TC 64, Electrical installations and
protection against electric shock, was submitted to the formal vote.
The combined texts were approved by CENELEC as HD 60364-4-43 on 2010-03-01.
This document supersedes HD 384.4.43 S2:2001 + corrigendum December 2005.
The main changes with respect to HD 384.4.43 S2:2001 are listed below:
– Introduction of new informative Annexes B, C and D.
– Information concerning flexible cables added to Scope.
– The word “phase” changed to “line” throughout the standard.
– Requirement not to distribute the neutral in IT systems changed to a NOTE.
– Requirements added for overload detection for the neutral conductor for harmonic currents.
– Requirement that devices for protection against short-circuit current be capable of making as well as
breaking short-circuit current added.
– Information added to clarify protection against overload current.
– Requirements where devices for protection against overload need not be provided expanded.
– More examples given where omission of devices for protection against overload is permitted.
– Requirements where devices for protection against short-circuit need not be provided expanded.
– Requirements for short-circuit current ratings of busbar trunking systems added.
