The C-curve (tripping characteristic C) means magnetic release between 5× and 10× In, so it's a fit for mixed resistive-inductive loads like small motor circuits, lighting banks, or control transformers where inrush won't nuisance-trip a B-curve but you still want fast fault clearing. ## Ratings and thermal derating Rated 32 A at 30 °C ambient, but the thermal derating curve is published per the datasheet: 30.08 A at 40 °C, 29.12 A at 45 °C, 27.84 A at 50 °C, and 25.92 A at 55 °C. Insulation voltage (Ui) is 264 V, surge voltage resistance rated at 4 kV, overvoltage category III, pollution degree 2 — standard for fixed-installation distribution boards.","metaTitle":"Siemens SENTRON 5SU9104-1KK32 RCBO, 32A, 10mA, Type AC, C-cu","metaDescription":"Siemens SENTRON 5SU9104-1KK32 RCBO, 32A rated, 10mA residual current, Type AC, C-curve, 10kA breaking capacity.
