It protects a single-phase final subcircuit against both overload/short-circuit (C-curve, 10 A rated) and earth leakage (30 mA, Type AC). The 30 mA sensitivity is the standard for personal protection against indirect contact in residential and commercial installations. ## Derating and installation constraints 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 (–). The IP20 rating applies only when the distribution board is installed with conductors connected — so it's not a standalone outdoor device. Depth is 77 mm, installation depth 70 mm; verify gland-plate clearance in shallow enclosures.","metaTitle":"Siemens 5SU9304-1KK10 SENTRON RCBO, 10 A, 30 mA, Type AC, C-","metaDescription":"Siemens SENTRON 5SU9304-1KK10 RCBO, 1P+N, 10 A rated, 30 mA residual, C-curve, 10 kA breaking capacity per EN 60898.
