Chint 20A B Curve 30mA Type A RCBO AFDD

The CHINT NB3LE-AFD-B20 is an advanced Arc Fault Detection Device (AFDD) with integrated RCBO protection, designed to provide comprehensive electrical safety in residential, commercial, and light industrial installations. Combining arc fault detection, overload protection, short-circuit protection, and residual current protection within a single compact device, it delivers enhanced protection against electrical faults and potential fire hazards caused by damaged wiring, loose connections, or insulation deterioration.

Part of the advanced NB3LE-AFD range from CHINT, the NB3LE-AFD-B20 is rated at 20A with a B Curve tripping characteristic, making it ideal for lighting circuits, socket outlets, and general-purpose electrical circuits with low inrush currents. The integrated AFDD technology continuously monitors electrical waveforms and automatically disconnects the circuit if dangerous arc faults are detected, helping prevent electrical fires before they occur.

This multifunction device combines the capabilities of an AFDD, MCB, and Type A RCBO into one compact module, helping save valuable space within consumer units and distribution boards while improving overall installation safety and reliability.
