The 16 A rating holds only at 30 °C ambient. In a crowded enclosure at 40 °C the continuous current drops to 15.2 A; at 50 °C it's 14.4 A; at 60 °C it's 13.6 A; at 70 °C it's 12.32 A. Mounting position is unrestricted, so vertical or horizontal DIN-rail orientation does not affect the derating curve.","metaTitle":"Siemens SENTRON 5SU1354-1LB16 RCBO, 16A, C-curve, 10kA","metaDescription":"Siemens SENTRON 5SU1354-1LB16 RCBO, 1P+N, 16A rated at 30°C, C tripping characteristic, 10kA breaking capacity per EN 60898, 20kA per IEC 60947-2.
