FuseBox RTAMB25BD Mini RCBO 25A 30mA

The FuseBox RTAMB25BD is a compact 25A Type A Bi-Directional RCBO designed to provide combined protection against overload, short circuit faults, and earth leakage in modern electrical installations. It integrates the functions of an MCB and RCD into a single device, offering space-saving protection for FuseBox consumer units.

Rated at 25A with a 30mA residual operating current, the RTAMB25BD features a B-curve tripping characteristic and a 6kA breaking capacity, ensuring reliable performance in residential and light commercial circuits. Its Type A sensitivity allows detection of AC and pulsating DC fault currents, making it suitable for modern electronic loads and appliances.

A key feature of the RTAMB25BD is its bi-directional capability, allowing current flow in either direction. This makes it particularly suitable for installations with renewable energy systems such as solar PV or battery storage, where power flow may reverse. The device also provides 1P+N switching (switched neutral) for improved isolation and safety.

Designed for use in FuseBox consumer units, the RTAMB25BD is DIN rail mountable and compact in form, helping reduce wiring complexity and improve installation efficiency. It complies with IEC 61009-1 and IEC 61009-2-2 standards, ensuring conformity with modern electrical safety requirements.
