Application Summary AI generated

This standard provides a framework for analyzing fire risks associated with low-voltage switchgear and controlgear assemblies, and specifies measures to mitigate those risks. It is applied by manufacturers and engineers in industrial and commercial electrical installations to evaluate potential ignition sources, such as arcing faults or overheating, and to implement design or protective solutions. The standard is particularly relevant for ensuring compliance with fire safety regulations in power distribution systems, control panels, and similar equipment operating up to 1000 V AC or 1500 V DC.
