Application Summary AI generated
GB/T 22387-2016 specifies technical requirements, test methods, and performance criteria for residual current operated relays used in low-voltage electrical systems. It applies to relays that detect leakage currents and trigger protective actions, commonly employed in industrial distribution panels, building electrical installations, and power supply systems to prevent electric shock and fire hazards. The standard ensures reliable operation under varying conditions, such as in environments with harmonic currents or transient surges.
