Chint 6A B Curve RCBO 30mA 1 Pole + Neutral

The CHINT NB1L-B06 is a compact and highly sensitive Residual Current Circuit Breaker with Overcurrent Protection (RCBO) designed to deliver reliable electrical safety in a single modular device. It integrates the functions of a Miniature Circuit Breaker (MCB) and a Residual Current Device (RCD), providing full protection against overload, short-circuit faults, and earth leakage currents.

As part of CHINT’s NB1L series, the B06 model is specifically rated at 6A, making it ideal for low-current and precision electrical applications where sensitive protection is required. It is commonly used in lighting circuits, control systems, alarm circuits, and small auxiliary loads in residential, commercial, and light industrial installations.

The device features a Type B tripping curve, ensuring fast response to fault conditions while maintaining stability under normal operating loads. With a typical 30mA residual current sensitivity, it provides enhanced personal protection against electric shock and reduces fire risks caused by insulation failure or leakage currents.

Designed in accordance with IEC/EN 61009-1 standards, the NB1L-B06 ensures dependable performance, high safety compliance, and long service life. Its compact DIN rail-mounted modular design allows for easy installation and efficient use of space within modern distribution boards, making it especially suitable for installations where panel space is limited.
