Põhitekst
IEC 60947-9-2:2021 covers internal arc-fault control devices, hereinafter referred to as IACD, which are intended to: – detect internal arc-faults in low-voltage switchgear and controlgear assemblies, by processing (at a minimum) the optical effect of an internal arc-fault, and – operate mitigation device (either external or combined) in order to minimize the effects of the internal arc-fault.
