Chint 10A B Curve RCBO 30mA 1 Pole + Neutral

The CHINT NB1L-B10 is a compact and highly reliable Residual Current Circuit Breaker with Overcurrent Protection (RCBO) designed to provide complete electrical safety in a single modular device. It integrates the functions of an MCB (Miniature Circuit Breaker) and an RCD (Residual Current Device), offering protection against overload, short-circuit faults, and earth leakage currents within a single unit.

Engineered for modern electrical distribution systems, the NB1L-B10 is ideal for applications requiring lower current ratings, particularly in lighting circuits, control circuits, and sensitive electrical loads. With its 10A rated current, it is well suited for low-load final circuits in residential, commercial, and light industrial environments where precision protection and reliability are essential.

The device features a Type B tripping curve, providing fast and efficient disconnection during fault conditions, especially in circuits with standard inrush current characteristics. It also typically incorporates 30mA residual current sensitivity, ensuring a high level of personal protection against electric shock and reducing the risk of fire caused by leakage currents.

Built to comply with IEC/EN 61009-1 standards, the NB1L-B10 ensures dependable performance, long electrical life, and consistent protection even under demanding operating conditions. Its compact DIN rail-mounted design allows for easy installation and efficient use of space in distribution boards, making it ideal for modern, space-constrained installations.
