Chint 32A B Curve 30mA Type A RCBO AFDD

The CHINT NB3LE-AFD-B32 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 one compact device, it delivers comprehensive circuit protection against electrical faults and fire hazards caused by damaged cables, loose connections, or deteriorating insulation.

Part of the advanced NB3LE-AFD range from CHINT, the NB3LE-AFD-B32 is rated at 32A with a B Curve tripping characteristic, making it particularly suitable for residential circuits, lighting circuits, socket outlets, and applications with lower inrush currents. The integrated AFDD technology continuously monitors electrical waveforms and automatically disconnects the circuit if dangerous arc faults are detected, helping reduce the risk of electrical fires before they occur.

This multifunction protection device combines the functionality of an AFDD, MCB, and Type A RCBO into a single space-saving module, helping improve installation safety while reducing the number of devices required within consumer units and distribution boards. The device is designed for AC 230/240V systems and complies with recognised IEC and BS EN safety standards
