The 30 mA sensitivity is the standard for personal protection against indirect contact in TN and TT systems. The higher IEC figure matters when the RCBO sits downstream of a transformer or in an industrial panel where prospective fault current can exceed the domestic 6 kA limit. The 15 kA rating gives it headroom for coordination with upstream devices in a selective scheme. In a real panel — say 40 °C to 50 °C — the continuous current must be derated: 9.5 A at 40 °C, 9 A at 50 °C, 8.5 A at 60 °C, and 8 A at 70 °C. Plan the load at the derated value for the expected ambient, not the 30 °C nameplate figure. Mounting position is unrestricted — install it any orientation in the distribution board.","metaTitle":"Siemens 5SU1656-1KK10 SENTRON RCBO, 2-Pole, 10A C-Curve, 30m","metaDescription":"Siemens 5SU1656-1KK10 SENTRON RCBO. 2-pole, 10A rated, C-curve, 30mA AC residual current. 6kA (EN 60898) / 15kA (IEC 60947-2) breaking capacity.
