Chint 16A B Curve RCBO 30mA 1 Pole + Neutral

The CHINT NB1L-B16 is a compact, high-reliability Residual Current Circuit Breaker with Overcurrent Protection (RCBO) designed to provide complete electrical safety in a single modular device. It combines the functions of an MCB (overcurrent protection) and an RCD (earth leakage protection), ensuring effective protection against overload, short circuits, and earth leakage faults.

Engineered for modern electrical distribution systems, the NB1L-B16 is widely used in residential, commercial, and light industrial installations where space efficiency and enhanced safety are essential. Its integrated design reduces wiring complexity and saves valuable DIN rail space inside consumer units and distribution boards.

With a 16A rated current, the B16 model is ideally suited for lighting circuits, socket outlets, and general-purpose final circuits with low to moderate electrical loads. The Type B tripping curve ensures fast disconnection in the event of fault conditions, making it well-suited for standard domestic applications where rapid response is critical for safety.

The device typically offers a 30mA residual current sensitivity, providing a high level of personal protection against electric shock. Built in compliance with IEC 61009-1 standards, it ensures dependable performance, electrical durability, and consistent operation even under demanding conditions.
