Live Electrical RA120B-030 20A RCBO B Curve, A Rated 10kA 30mA 20 Amp

The RA120B-030 is a compact 20A single-module RCBO from LIVE Electrical, designed to provide combined protection against overload, short circuit, and earth leakage faults in one device. It uses Type A residual current detection, meaning it can respond to both AC and pulsating DC leakage currents, making it suitable for modern electrical installations with electronic loads such as LED lighting, appliances, and inverter-driven equipment. Its high immunity design helps reduce nuisance tripping caused by harmonics or transient surges.
