FuseBox RTAMB25 Mini RCBO 25A 6kA

The FuseBox RTAMB25 is a compact 25A mini RCBO (Residual Current Breaker with Overcurrent Protection) designed to provide combined protection against overloads, short circuits, and earth leakage faults in residential and light commercial electrical installations. By integrating MCB and RCD functionality into a single-module device, it helps maximise available space within consumer units while ensuring enhanced electrical safety.

Featuring a B Curve tripping characteristic, the RTAMB25 is ideally suited for circuits with low inrush currents, including lighting, heating controls, and general-purpose socket circuits. Its Type A residual current protection detects both AC and pulsating DC fault currents, making it suitable for modern installations containing electronic equipment and appliances.

With a 6kA short-circuit breaking capacity and 30mA residual operating current, the RTAMB25 provides reliable protection against electric shock and fire risks. The device incorporates double-pole switching (switched live and neutral) for enhanced isolation and safety. Designed specifically for use with FuseBox consumer units, it features a compact single-module format with a flying neutral lead for fast and efficient installation. It complies with IEC/EN 61009-1 and IEC/EN 61009-2-2 standards, supporting compliance with current wiring regulations and 18th Edition requirements.
