Fusebox 1P+N Mini Bidirectional RCBO (RTAMB**BD)

Description

The Fusebox RTAMB**BD is a compact, 1-module bidirectional Type A Mini RCBO designed for modern electrical installations. Offering various amperages, B Curve protection with a 6kA breaking capacity and 30mA tripping sensitivity, this device provides crucial dual protection against overloads, short circuits, and earth leakage faults. Engineered with switched Live and Neutral (1P+N) for total isolation, its bidirectional functionality makes it fully compliant and optimized for solar PV generation, EV charging points, and battery storage setups where power flows in both directions.

Key Features & Benefits

Future-Proof Bidirectional Protection: Specifically designed to detect and interrupt fault currents flowing from both source-to-load and load-to-source. Essential for renewable energy generation (Solar PV), home battery storage, and EV chargers.

Space-Saving Mini Design: At only 18mm wide (1 module) and matching the height of a standard MCB, it maximizes internal wiring and terminal space inside the Fusebox consumer unit for a cleaner, faster install.

Switched Pole & Neutral (1P+N): Switches both the live and neutral lines simultaneously. This offers comprehensive circuit isolation, making fault finding easier and preventing the need to disconnect neutrals during insulation resistance testing.

Type A Sensitivity: Offers robust protection by detecting both standard AC and pulsating DC residual fault currents (up to 6mA), which are commonly generated by modern household electronics and green energy systems.

Installer-Friendly Fitting: Features a 450mm flying neutral tail that can easily be cut to length and neatly terminated to suit the layout of the board.
