Chint 20A C Curve 30mA Type A RCBO AFDD

The CHINT NB3LE-AFD-C20 is an advanced Arc Fault Detection Device (AFDD) with integrated RCBO protection, designed to provide enhanced 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 unit, this device offers comprehensive protection against electrical faults and potential fire hazards caused by damaged cables, loose connections, or deteriorating insulation.

Part of the advanced NB3LE-AFD range from CHINT, the NB3LE-AFD-C20 is rated at 20A with a C Curve tripping characteristic, making it suitable for circuits with moderate inrush currents such as socket outlets, appliances, small motors, and inductive loads. The built-in AFDD technology continuously monitors the electrical waveform and disconnects the circuit automatically if dangerous arc faults are detected, helping prevent electrical fires before they occur.

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