Chint 32A B Curve RCBO 30mA Type AC 10kA 1 Pole + Neutral

The Chint NB3LEU-B32 is a compact and high-performance 1 Pole + Neutral RCBO (Residual Current Breaker with Overcurrent Protection) designed to provide complete circuit protection in a single modular device. It combines earth leakage protection, overload protection, and short-circuit protection, making it ideal for modern residential and commercial distribution boards where safety and space efficiency are essential.

With a 32A rated current, 30mA residual sensitivity, and B Curve tripping characteristic, this RCBO is suited to circuits with low inrush currents such as lighting, socket outlets, and general-purpose final circuits. The 30mA sensitivity provides additional personal protection against electric shock, while also helping reduce fire risk from insulation faults.

This device is part of the Chint NB3LEU series, which is widely used for installations requiring compact, compliant protection devices that meet modern IEC safety standards.
