The 20 A rating is at 30 °C; at 40 °C it derates to 18.8 A, at 50 °C to 17.4 A — so if the panel ambient runs warm, size the branch circuit load accordingly. The D curve means magnetic trip occurs at 10–20× In (200–400 A), so it won't nuisance-trip on motor inrush or transformer magnetizing current. The 30 mA residual-current threshold meets standard personnel protection requirements (IEC 60364). Touch protection is built in. The 77 mm depth plus 70 mm installation depth means it sits flush in a standard 80 mm deep distribution board.","metaTitle":"Siemens 5SU9354-8KK20 SENTRON RCBO, 2P, 20 A, 30 mA, Type A,","metaDescription":"Siemens 5SU9354-8KK20 SENTRON RCBO, 2-pole, 20 A rated, 30 mA Type A residual current, 10 kA breaking capacity, D characteristic.
