Chint 40A C Curve RCBO 30mA 6kA 1 Pole + Neutral

The CHINT NB3LEG-40-C40 is a compact and reliable RCBO (Residual Current Circuit Breaker with Overcurrent Protection) designed to provide advanced electrical safety for residential, commercial, and light industrial installations. Combining the functions of an MCB and RCD in a single device, the NB3LEG-40-C40 protects circuits against overloads, short circuits, earth leakage faults, and electric shock hazards. Featuring a C Curve tripping characteristic, 40A rated current, 30mA sensitivity, and 6kA breaking capacity, it is ideal for circuits with moderate inrush currents such as lighting, socket outlets, and small motor loads. Its Type A protection allows detection of both AC and pulsating DC residual currents, making it suitable for modern electrical systems containing electronic equipment. Designed for quick DIN rail installation and long-term dependable performance, the NB3LEG-40-C40 offers efficient protection while helping maintain compliance with modern electrical safety standards.
