Rated 40 A at 30 °C ambient, it derates to 37.6 A at 40 °C and 32.4 A at 55 °C — the thermal curve matters when the panel runs hot. The IP20 rating applies once installed in a distribution board with connected conductors — not for open-panel or wet-area use. The 1P+N design protects the phase conductor only; the neutral is switched but not protected — standard for single-phase RCBOs in TN or TT systems. The 2 MW width (36 mm) occupies two 18 mm DIN spaces, so factor that into your enclosure fill count. The 4 kV surge voltage resistance covers typical mains transients. The 1 kA surge current withstand (8/20 µs) handles lightning-induced spikes on the line side.","metaTitle":"Siemens 5SU9354-7KK40 SENTRON RCBO, 40 A, 10 kA, Type C","metaDescription":"Siemens 5SU9354-7KK40 SENTRON RCD-operated circuit breaker, 40 A rated at 30 °C, 10 kA breaking capacity per EN 60898, Type C characteristic, 1P+N, 2 MW.
