It protects a single-phase final subcircuit at 10 A rated current with a Type B tripping characteristic, meaning it handles both resistive and moderate inductive loads without nuisance trips. Rated voltage is AC only, 1P+N configuration with one protected pole. At 40 °C it derates to 9.4 A, at 45 °C to 9.1 A, at 50 °C to 8.7 A, and at 55 °C to 8.1 A. ## Wire range and panel fit Terminals accept 0.75 to 35 mm² solid or stranded copper — covers everything from a 1.5 mm² lighting circuit to a 10 mm² feeder. Mounts in any position, which simplifies layout in tight enclosures. IP20 with conductors connected and the distribution board installed. Rated overvoltage category III, energy limiting class 3. Halogen-free and silicon-free construction. Touch protection is built in. The product is classified as F per DIN EN 61346-2 and DIN EN 81346-2. Power supply cord position can be top or bottom — no orientation restriction.","metaTitle":"Siemens 5SU9404-0KK10 SENTRON RCD MCB, 1P+N 10A Type B 10kA","metaDescription":"Siemens SENTRON 5SU9404-0KK10 RCD-operated circuit breaker, 1P+N, 10 A, Type B, 10 kA per EN 60898.
