It is rated 10 A at AC with a C tripping characteristic, meaning it handles moderate inrush from motor or lighting loads without nuisance tripping, while still clearing short circuits up to 6 kA per EN 60898 and 10 kA per IEC 60947-2. ## Current derating and ambient limits Above that, derate linearly: 9.4 A at 40 °C, 9.1 A at 45 °C, 8.7 A at 50 °C, and 8.1 A at 55 °C. The operating ambient range is -25 to +45 °C, so at the upper end you are already at 9.1 A continuous — factor that into panel loading if the enclosure runs warm. Storage range is -40 to +75 °C, which is wider than the operating range; that limit governs handling and shelf life, not running conditions. The 5SU9356-1CS10 occupies 2 width units (36 mm) on a DIN rail, with an installation depth of 70 mm and overall depth of 77 mm. It accepts solid or stranded conductors from 0.75 mm² up to 35 mm² — that covers everything from a 1.5 mm² lighting circuit to a 10 mm² feeder.","metaTitle":"Siemens 5SU9356-1CS10 SENTRON RCD Circuit Breaker, 10 A, C-C","metaDescription":"Siemens SENTRON 5SU9356-1CS10 RCD-operated circuit breaker, 10 A rated, C tripping characteristic, 1P+N, 6 kA (EN 60898) / 10 kA (IEC 60947-2), 50 Hz.
