The CHINT NB2LE (RCBO) provides combined protection against overload, short-circuit, and residual current faults in AC 230/240 V circuits. Designed for industrial, commercial, and residential applications, it automatically disconnects the power supply upon leakage or electric shock, ensuring maximum safety. With 4.5 kA breaking capacity and leakage sensitivities of 30mA, the NB2LE is reliable, compact, and compliant with IEC/EN 61009-1 standards. 

Tripping Curve: Type C trips magnetically at approximately 5 to 10 times the rated current (In), while providing thermal tripping for overload conditions. It offers a balance between sensitivity and tolerance to moderate inrush currents.

Tripping class: Type A class detects & trips on AC sinusoidal residual currents and pulsating DC residual currents, ensuring protection where electronic loads may produce DC components. It provides standard earth leakage protection (e.g., 30 mA) with fast disconnection.
