BG RCBO 40A C Curve Type A Double Pole Bi-Directional 6kA CUCRC40DPA

BG CUCRC40DPA — 40A C Curve Type A Bidirectional RCBO (30mA, Double-Pole)

The BG Fortress CUCRC40DPA is a high-performance 40A C-curve bidirectional RCBO that combines overcurrent protection (MCB) and earth-leakage protection (RCD) in a single, space-saving module. Designed for modern domestic and light-commercial electrical installations, this RCBO delivers 30mA Type A residual current protection, making it suitable for circuits serving electronic loads and devices with pulsed DC components.

Its bidirectional design supports circuits where current may flow in either direction — such as those with renewable generation or energy storage systems — while still providing comprehensive protection for lighting, socket and appliance circuits in conjunction with BG consumer units and DIN-rail boards.

The CUCRC40DPA-01 integrates two essential protective functions in one:

Residual-current protection with a 30 mA trip threshold to guard against electric shock and leakage faults.

Circuit-breaking protection with a C-curve characteristic for overload and short-circuit events.

Its double-pole isolation disconnects both live and neutral simultaneously during a fault — delivering added safety and compliance with BS 7671 Wiring Regulations.

Installer-Friendly Design & Everyday Safety

The RCBO’s single module width maximises available space within consumer units and distribution boards. It includes a manual test button for routine functional checks and an integrated neutral lead for easier wiring during installation. Compatible with standard 35 mm DIN rails, the unit is a practical choice for professional electricians fitting modern electrical systems.
