It combines overcurrent protection and 30 mA residual current protection in a single 36 mm wide (2 MW) module, saving a DIN-rail position versus separate MCB + RCD. The 30 mA residual-current element covers personnel protection and fire prevention. Snap-on mounting to DIN rail. Mounting position is any. Terminals accept 0.75 mm² to 25 mm² conductors. Touch protection is provided on the terminals. ## Thermal derating and environmental limits Current rating is temperature-dependent: 10 A at 30 °C, derating to 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. In a warm panel (40 °C+), size the load circuit accordingly — the 10 A nameplate applies only at 30 °C ambient. Halogen-free and silicon-free construction. Rated for up to 95% humidity. Overvoltage category III (fixed installation, distribution level). Energy limiting class 3 — fast enough to limit let-through energy for downstream equipment protection.","metaTitle":"Siemens 5SU9356-1CR10 SENTRON RCBO, 10 A, 30 mA, Type C","metaDescription":"Siemens 5SU9356-1CR10 SENTRON RCD-operated circuit breaker (RCBO), 10 A rated, 30 mA residual current, Type C characteristic, 6 kA (EN 60898) / 10 kA (IEC 60947-2).
