BG RCBO 40A Bi-Directional Double Pole Type B 6kA CUCRB40DPA

BG CUCRB40DPA-01 40A Bidirectional RCBO Type A 30mA – Compact, Safe Circuit Protection

Ensure circuit safety with BG CUCRB40DPA-01 40A Bidirectional RCBO, a compact residual current breaker with overcurrent protection designed for safe electrical solutions. This single module RCBO features Type A 30mA sensitivity with a <0.1s trip speed and 6kA breaking capacity, offering robust protection against short circuits, overloads and earth leakage for both AC and pulsating DC currents. Its bidirectional design is ideal for PV/solar applications and EV charging systems, where current flows in two directions.

Crafted for BG consumer units, this 2-pole RCBO with an integrated blue neutral lead ensures easy installation via a 35mm DIN rail. Backed by a 10-year warranty, the BG CUCRB40DPA-01 combines energy-efficient circuit protection with compliance to BS 7671:2018 Amendment 3, making it perfect for homeowners, electricians and solar installers. 

Bidirectional Protection: Type A RCBO with >6mA pulsed DC detection ensures safe circuit protection for systems with bidirectional current flow, such as solar PV systems and EV chargers. 

Compact Design: Single module (18mm) fits seamlessly into BG consumer units, maximising wiring space for compact electrical installations. 

Fast and Safe Response: 30mA sensitivity and <0.1s trip speed provide rapid protection against earth faults and overcurrents, ideal for safe RCBOs in domestic and commercial settings. 

Easy Installation: Integrated blue neutral lead (480mm, 4mm²), backed-out Pozidrive 2 screws, and DIN rail mounting simplify setup, with L2: 2Nm, L1/N1: 1.2Nm torque for secure connections. 

Robust Performance: 6kA breaking capacity, B curve tripping (3–5 times rated current), and 230V operational voltage ensure reliability for modern electrical systems. 

Durable and Certified: Pollution Degree 3 tested, operates in -25°C to +40°C, with IP20 rating and compliance to BS EN 61009-1, UKCA, and CE standards for reliable circuit breakers. 

Versatile Applications: Supports 16mm² (L2) and 10mm² (L1/N1) cable capacities, ideal for home electrical upgrades, solar installations, and commercial circuit protection.
