It protects a single-phase final subcircuit against overload, short-circuit, and earth leakage in one unit, saving a DIN-rail position versus separate RCD and MCB. The RCBO is instantaneous design — no intentional time delay on the residual-current element — so it trips within 40 ms on a ground fault. That makes it suitable for circuits where fast disconnection is required, but not for selective coordination with upstream time-delayed RCDs.
Installation depth is 70 mm plus the 77 mm overall depth, so the RCBO protrudes 77 mm from the rail. The IP20 rating applies once the distribution board is installed with conductors connected — meaning the front face is touch-safe, but the terminals are not protected against water ingress. The temperature derating curve is published: at 40 °C the continuous current drops to 9.5 A, at 50 °C to 9 A, and at 70 °C to 8 A.
For compliance documentation, the brand provides a CE declaration of conformity and the product is designed to EN 60898 and IEC 60947-2. Halogen-free and silicon-free construction is specified. Specific RoHS/REACH statements are available on request with the RFQ.
