Scope

Main technical content: This standard specifies the terms and definitions, usage conditions, basic requirements, classification, standard rated values, technical requirements, test methods, inspection rules, packaging, transportation and storage, and quality commitments for surge protectors used in low-voltage distribution systems. This standard applies to indoor low-voltage distribution system surge protectors (hereinafter referred to as SPD) used to protect against indirect lightning and direct lightning effects or other transient overvoltages. SPDs must contain at least one non-linear component used to limit voltage and discharge surge currents. After assembly, SPDs are connected to circuits and equipment with an AC rated voltage of no more than 1,000 V (rms) and a frequency of 50/60 Hz.
