BG RCBO 6A Bi-Directional Double Pole B Curve 6kA CUCRB6DPA

BG CUCRB6DPA — 6A B Curve Type A Bidirectional Double-Pole RCBO (30mA, 6kA)

The BG Fortress CUCRB6DPA is a 6A B-curve, Type A bidirectional RCBO designed to provide sensitive protection for lighting and low-load domestic circuits. Combining overload, short-circuit and 30mA residual-current protection in a compact single-module device, it ensures safe, reliable disconnection of both live and neutral poles during a fault.

Its bidirectional capability makes it suitable not only for standard installations but also for circuits where current may flow in either direction—such as solar PV, battery storage and microgeneration systems.

Precision Protection for Low-Load Circuits

The 6A B-curve trip characteristic provides fast, stable protection for small lighting groups, control circuits and low-inrush devices. Additional built-in safety features include:

30mA Type A RCD protection with detection of AC and >6mA pulsed DC leakage

6kA breaking capacity for dependable fault interruption

This ensures the CUCRB6DPA meets the demands of modern low-current circuits while maintaining compliance with BS 7671.

Installer-Friendly Compact Design

35mm DIN-rail mounting

Pozidrive terminal screws for secure terminations

480mm, 4mm² neutral tail supplied

Front-facing test button for routine RCD checks

Rated for operation in –25°C to +40°C environments and tested to Pollution Degree 3, the CUCRB6DPA is robust enough for harsher locations such as utility rooms or garages.
