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.

• Complies with IEC/EN 61009-1 safety standard for RCBOs. Ensures the device provides reliable protection against electric shock, overload and short circuits, and meets strict performance and safety requirements for electrical safety.
• Type A class Trip on both AC and pulsing DC leakage currents, whether they rise quickly or slowly, ensuring reliable protection for modern electrical load. 
• C- Curve breakers allow short bursts of higher current (like equipment starts up) without tripping, but still protect the circuit from overloads and faults.
• 10kA breaking capacity ensures reliable performance in installations with higher fault levels.
• Mounting: DIN rail EN 60715 (35mm) by means of a fast clip device 
• Connection: From bottom
