BG RCBO 25A Bi-Directional Double Pole B Curve 6kA CUCRB25DPA

BG CUCRB25DPA — 25A B Curve Type A Double-Pole Bidirectional RCBO (30mA, 6kA)

The BG Fortress CUCRB25DPA is a 25A B-curve, double-pole, Type A RCBO engineered to deliver combined residual-current and overcurrent protection in a compact, installer-friendly 1-module design. With bidirectional capability, it safely supports applications where current can flow in either direction — making it suitable not only for standard domestic circuits but also for solar PV, battery storage and other generation-linked systems.

The device provides 30mA Type A RCD protection, detecting AC and >6mA pulsed DC leakage, and a 6kA breaking capacity, ensuring strong fault protection for lighting, socket and appliance circuits.

Robust Double-Pole Isolation for Safer Installations

Unlike single-pole devices, the CUCRB25DPA-01 disconnects both live and neutral during a fault event, improving safety and fault discrimination — particularly valuable in circuits with shared neutrals or sensitive connected equipment.

This makes it an ideal choice for electricians seeking compliance with BS 7671 and Amendment 3 safety requirements.

Compact 1-Module Design with Installer-Friendly Features

The RCBO fits any BG consumer unit or DIN-rail enclosure thanks to its single-module width and 35mm rail compatibility.

Practical installation features include:

Pozidrive PZ2 terminal screws for secure fastening

Integrated 480mm neutral tail (4mm²) for quick wiring

Clear front test button for routine safety testing

Operating temperature from -25°C to +40°C, suitable for challenging environments
