Rated 10 A with a Type C tripping characteristic. Residual-current element is Type AC, 100 mA sensitivity.
The 20 kA figure gives headroom for high-fault installations — a 10 kA board with a 20 kA device means the RCBO clears a fault before the upstream main breaker sees it, preserving selectivity. Energy limitation class 3 means it lets through less energy than a class-1 or class-2 device, reducing arc-flash risk and thermal stress on downstream wiring.
Neutral conductor is switched internally (1P+N), so the neutral pole opens with the line pole, meeting disconnection requirements for single-phase circuits.
