The CHINT NB3LEU-63 RCBO is a high-performance protective device designed for three-phase electrical systems, combining overcurrent and residual current protection in one unit. With a 3P+N configuration and compact 3-module chassis, it delivers efficient protection while optimising switchboard space.

This NB3LEU-63 3P+N RCBO with 10A rating, 30mA sensitivity, and 10kA capacity. Type A C-curve protection for three-phase systems. This RCBO provides effective protection against overloads, short circuits, and earth leakage, helping to prevent electric shock and equipment damage. The 10kA breaking capacity ensures reliable performance in installations with higher fault levels. The C-curve tripping allows the device to handle moderate inrush currents, making it suitable for a wide range of commercial and industrial applications. The Type A class Trip on both AC and pulsing DC leakage currents, whether they rise quickly or slowly, ensuring reliable protection for modern electrical loads.
