It breaks fault currents up to 10 kA per EN 60898 and IEC 60947-2, so it handles typical commercial and industrial branch-circuit faults without upstream coordination issues. ## Thermal derating and installation constraints At 40 °C ambient the 125 A rating derates to 115.62 A; at 50 °C it drops to 106.25 A, and at 60 °C to 96.25 A. That means a panel running near 50 °C loses roughly 15% of the headline capacity — factor that into the load schedule before committing the BOM line. The unit occupies 7 modular width units (roughly 126 mm) on a DIN rail and mounts in any position, with a 70 mm installation depth. Halogen-free and silicon-free construction suits installations where outgassing or contamination risk matters (e.g., clean rooms, medical environments). Operating temperature range spans -40 °C to 75 °C, with max 95% humidity influence.","metaTitle":"Siemens 5SU1324-1KK82 SENTRON RCBO, 2P, 125 A, 30 mA, C-curv","metaDescription":"Siemens 5SU1324-1KK82 SENTRON RCBO, 2-pole, 125 A rated, 30 mA residual current, C characteristic, 10 kA breaking capacity.
