7.1 General
7.2 Circuit protection
7.3 Short-circuit protection for LV assemblies
7.4 Short-circuit protection for controlgear
7.5 Short-circuit protection using circuit-breakers
for household and similar installations to
IEC 60898-1 (usually known as MCBs) and residual
current operated circuit-breakers with integral
overcurrent protection (RCBOs) to IEC 61009-1
Annex A (informative) Interpolation of the suitability of
an alternative SCPD for the protection
of controlgear (substitution)
Describes an application guide for the short-circuit ratings given in IEC standards for low-voltage switchgear and controlgear and assemblies, summarises the definitions of the ratings and provides examples of their application.
