The derating curve is published, so you can size it properly at the design stage rather than chasing nuisance trips in the field. The 54 mm width (3 modular units) means it occupies three 18 mm slots; plan your rail fill accordingly if you're retrofitting into an existing board.","metaTitle":"Siemens 5SU1324-6KX32 SENTRON RCBO, 32 A Type B, 30 mA, 10 k","metaDescription":"Siemens 5SU1324-6KX32 SENTRON RCBO, 2-pole, 32 A, Type B curve, 30 mA residual current, 10 kA breaking capacity (EN 60898).
