Scolmore Elucian CU1RCBOD20B Description
The Scolmore Elucian CU1RCBOD20B Bi-Directional RCBO combines earth fault, overcurrent and short-circuit protection within one compact device. Rated at 20A with a B Curve tripping characteristic and 30mA residual current sensitivity, this Type A RCBO provides individual circuit protection while occupying just a single module within a compatible Elucian consumer unit.
Its bi-directional design allows current to flow through the device in either direction, providing additional flexibility for modern electrical systems where power flow may not always be one-way. The 1 pole + switched neutral configuration switches both line and neutral, while Type A residual current protection is designed to detect both AC and pulsating DC residual currents.
With a true 6kA breaking capacity, 240V AC operating voltage and compact 17.8mm width, the CU1RCBOD20B provides comprehensive circuit protection without taking up unnecessary consumer unit space. Large terminal capacities and a 450mm neutral tail further enhance installation flexibility, making this 20A Elucian RCBO a practical choice for domestic and commercial circuit protection applications.
