FuseBox RTAMB40BD Mini RCBO 40A 30mA

The FuseBox RTAMB40BD is a compact 40A Type A Bi-Directional RCBO designed to provide combined protection against overloads, short circuits, and earth leakage faults in modern electrical installations. Combining the functions of an MCB and RCD within a single device, it offers comprehensive circuit protection while saving valuable space within consumer units.

Rated at 40A with a 30mA residual operating current, the RTAMB40BD features a B-curve tripping characteristic and a 6kA breaking capacity, making it suitable for residential and light commercial applications. Its Type A sensitivity enables detection of both AC and pulsating DC fault currents, providing enhanced protection for modern electrical equipment and appliances.

The unit incorporates bi-directional technology, allowing power to flow in either direction, making it particularly suitable for installations incorporating solar PV systems, battery storage, and other energy management solutions. The 1P+N switched neutral (double-pole switching) design disconnects both live and neutral conductors for improved safety.
