GB/T 32902-2016
ActiveCircuit-breakers incorporating residual current protection with auto-reclosing functions（CBAR)
具有自动重合闸功能的剩余电流保护断路器（CBAR）
Application Summary AI generated
This standard specifies the technical requirements, test methods, and performance criteria for circuit-breakers that combine residual current protection with automatic reclosing functionality. It is applied in low-voltage distribution systems, particularly in residential, commercial, and industrial settings where automatic restoration of power is desired after a transient fault, such as in outdoor lighting, power distribution cabinets, or remote monitoring systems. The standard ensures these devices reliably detect earth leakage currents, trip to prevent electric shock or fire, and then automatically reclose the circuit when the fault clears.
