Chint 25A B Curve 30mA Type A RCBO AFDD

The CHINT NB3LE-AFD-B25 is an advanced Arc Fault Detection Device (AFDD) with integrated RCBO protection, designed to provide comprehensive electrical safety for 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 helps safeguard electrical systems against dangerous faults and electrical fires caused by damaged wiring, loose connections, or deteriorating insulation.

Part of the advanced NB3LE-AFD range from CHINT, the NB3LE-AFD-B25 is rated at 25A with a B Curve tripping characteristic, making it ideal for lighting circuits, socket outlets, and general-purpose electrical circuits with lower inrush currents. The integrated AFDD technology continuously monitors electrical waveforms and disconnects the circuit automatically when dangerous arc faults are detected, helping reduce the risk of electrical fires before they occur.

This multifunction protection 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.
