It is a 2-pole device occupying 4 modular width units (72 mm wide) for DIN-rail mounting in distribution boards. ## Key ratings and their meaning for fit The 40 A rated current at AC combined with the C characteristic means this RCBO is sized for circuits with moderate inrush — typically motor or lighting loads in commercial or industrial final subcircuits — where the magnetic trip threshold is 5 to 10 times rated current, avoiding nuisance trips on startup. Breaking capacity is rated at 10 kA per EN 60898 and 15 kA per IEC 60947-2. The higher IEC figure applies when the RCBO is used as a circuit-breaker in industrial distribution; the EN figure governs domestic/commercial installations. ## Installation and environmental constraints The device is 72 mm wide (4 MW) and 70 mm deep, fitting standard DIN-rail enclosures.","metaTitle":"Siemens 5SU1324-1RC40 SENTRON RCBO, 40 A, 2-pole, C-curve, 3","metaDescription":"Siemens SENTRON 5SU1324-1RC40 RCBO: 40 A rated, 2-pole, C characteristic, 30 mA residual current, 10 kA (EN 60898) / 15 kA (IEC 60947-2) breaking capacity.
