Understanding IEC 61641: The Standard for Internal Arc Fault Protection in Low-Voltage Switchgear Scope and Purpose of IEC 61641 I can

Provides personnel protection by ensuring that effects of an internal arc (like hot gases or fragments) are directed away from operators.

IEC TR 61641 represents a critical resource for anyone involved in the design, manufacture, specification, or operation of low-voltage switchgear and controlgear assemblies. While it is a voluntary technical report rather than a mandatory standard, its guidance has become the industry benchmark for assessing internal arc fault capability.
