The 20 A rating is thermally calibrated at 30 °C ambient; at 40 °C the continuous current derates to 18.8 A, at 50 °C to 17.4 A, and at 70 °C to 14.6 A — factor this into panel thermal design if the distribution board runs warm. For installations where the available fault current exceeds 10 kA, an upstream current-limiting MCB or fuse is required to coordinate selectivity. Mounting position is unrestricted. Supply can enter from either top or bottom.","metaTitle":"Siemens 5SU1324-6FA20 SENTRON RCBO, 20 A, 30 mA, B Curve","metaDescription":"Siemens 5SU1324-6FA20 SENTRON RCBO, 2-pole, 20 A rated, 30 mA residual, B curve, 10 kA breaking capacity.
