BG RCBO 20A Bi-Directional Double Pole B Curve 6kA CUCRB20DPA

BG CUCRB20DPA — 20A B Curve Type A Bidirectional Double-Pole RCBO (30mA, 6kA)

The BG Fortress CUCRB20DPA is a 20A B-curve, Type A bidirectional RCBO that provides advanced circuit and personal protection for modern domestic and light-commercial installations. Designed for systems where current may flow in both directions, such as solar PV, battery storage, and other microgeneration setups, this device delivers full overload, short-circuit and 30mA earth-leakage protection in a compact single-module housing.

Featuring double-pole isolation, the CUCRB20DPA disconnects both live and neutral conductors during faults, ensuring safer maintenance and full compliance with BS 7671 Amendment 3.

Robust B-Curve Protection for Power Circuits

The 20A rating with a B-curve trip characteristic makes this RCBO suitable for domestic lighting circuits and general-purpose power circuits where inrush currents are low. Key protective functions include:

30mA Type A RCD protection for shock prevention and detection of AC and >6mA pulsed DC leakage

6kA breaking capacity for dependable disconnection under fault conditions

This ensures reliable circuit performance, reduced nuisance tripping and safe operation under varying load conditions.

Space-Saving, Installer-Friendly Single-Module Design

DIN-rail 35mm mounting

Pozidrive terminals for secure cable termination

Neutral tail supplied (480mm, 4mm²)

Front-mounted test button (T) for routine testing

Rated for –25°C to +40°C and tested to Pollution Degree 3, it is suitable for harsher environments such as utility rooms, garages and outbuildings.
