FuseBox RTAMB20BD Mini RCBO 20A 30mA

The RTAMB20BD is a compact 20A bi-directional RCBO from FuseBox, designed to provide combined protection against overload, short circuit, and earth leakage faults. Featuring a Type A residual current device, it detects both AC and pulsating DC fault currents, making it suitable for modern electrical installations including solar PV systems, battery storage, and Vehicle-to-Load (V2L) applications where power can flow in both directions. Its single-module design maximises wiring space within consumer units while maintaining full compliance with current wiring regulations.
