Rated frequency is 50 Hz, so it's built for standard European utility grids. ## Derating and mounting The 20 A rating holds at 30 °C; at 40 °C it derates to 18.8 A, and at 50 °C to 17.4 A. The IP20 rating applies once the distribution board is installed with connected conductors — bare terminals are not touch-safe until the board is closed.","metaTitle":"Siemens 5SU1324-7FA20 SENTRON RCBO, 2-Pole, 20 A, 30 mA, Typ","metaDescription":"Siemens SENTRON 5SU1324-7FA20 RCBO, 2-pole, 20 A, 30 mA residual current, Type A, 10 kA breaking capacity.
