Cudis 10A B Curve Bi-Directional Type A RCBO 30mA 1P+N | ROSNBI110B

The Cudis 10A Bi-Directional RCBO is a compact 1-module Type A RCBO providing combined overload, short-circuit and residual current protection in a single device. Designed with switched live and neutral (1P+N) and bi-directional capability, it is ideal for modern installations including circuits where supply direction may vary.

With a 6kA breaking capacity, 30mA residual current sensitivity, and B curve tripping characteristic, this miniature RCBO delivers fast, reliable protection while saving valuable board space. The device mounts directly to DIN rail and supports both pin and fork busbar connections for installation flexibility.

Engineered with fire-resistant, high-impact plastic and a clear status indicator, built for safe, durable operation in residential and commercial distribution boards.
