The CNC YCB7NLE-63 3P+N RCBO Circuit Breaker is an advanced protection device designed to provide complete safety for three-phase electrical systems. This RCBO (Residual Current Circuit Breaker with Overcurrent Protection) integrates multiple protection functions into one compact unit, making it ideal for modern residential, commercial, and industrial applications.
With a rated current of up to 63A and support for AC 230/400V systems, this breaker delivers reliable protection against overloads, short circuits, and earth leakage faults. It continuously monitors current flow and instantly disconnects the circuit when leakage or abnormal conditions are detected, helping prevent electric shocks and fire hazards.
The 3P+N (three phase + neutral) configuration ensures full protection across all phases and neutral, making it suitable for balanced and unbalanced loads in three-phase networks. Its fast tripping response (≤0.1s) and high breaking capacity (around 4.5kA–6kA) ensure quick fault isolation and enhanced system safety.
This RCBO supports multiple tripping curves (B, C, D), allowing it to be used in various applications such as resistive loads, mixed loads, and inductive equipment. It also offers different residual current sensitivity options (30mA, 100mA, 300mA), providing flexibility for different safety requirements.
Built according to IEC 61009-1 standards, the CNC YCB7NLE-63 ensures long-term reliability, durability, and stable performance. Its compact DIN rail design allows easy installation in distribution boards, making it a practical choice for modern electrical systems.
