It protects a 16 A single-phase circuit against overload, short-circuit, and earth leakage, with a 30 mA type A residual-current trip that catches pulsating DC faults from electronics or variable-speed drives. Rated 10 kA breaking capacity per EN 60898, and 20 kA per IEC 60947-2 — the higher IEC figure matters when this RCBO sits in an industrial panel where the prospective fault current at the board exceeds 10 kA. Verify your line-to-neutral voltage before specifying.
Survives the nacelle — wide temperature and surge resilience
Rated for -40 °C to 75 °C ambient, this RCBO handles the thermal swing inside a turbine nacelle or outdoor enclosure without derating. The 4 kV surge voltage resistance and 1 kA surge current (8/20 µs) mean it takes lightning-induced transients on the line side — no up-tower swaps from a close strike.
Panel fit and compliance notes
IP20 rating applies once the distribution board is installed with connected conductors — the front face is finger-safe; the busbar area is not. Compliance documentation: the SENTRON series carries CE marking and is designed to EN 60898 and IEC 60947-2. RoHS and REACH declarations are standard with the product from Siemens. No UL listing is cited on this variant — verify for North American installations.
