Application Summary AI generated

This standard provides technical specifications for integrating internal arc-fault mitigation systems into power switchgear and controlgear assemblies (PSC-assemblies) that comply with GB/T 7251.2—2023. It is applied in the design, testing, and verification of low-voltage switchgear and controlgear used in industrial, commercial, and utility power distribution systems to enhance personnel safety and equipment protection during internal arc faults. The standard ensures that mitigation systems, such as arc containment or pressure relief devices, are effectively incorporated without compromising the assembly's performance or compliance.
