Live Electrical RA140B-030 40A RCBO B Curve, A Rated 10kA 30mA 40 Amp

The RA140B-030 is a compact 40A bi-directional RCBO from LIVE Electrical, designed to provide combined protection against overload, short circuit, and earth leakage faults in a single module device. It features Type A residual current detection, making it suitable for modern electrical installations where both AC and pulsating DC leakage currents may be present. Its bi-directional capability makes it especially suitable for renewable energy systems such as solar PV, battery storage, and other installations with reverse power flow.
