  characteristics
  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.
