Rated 25 A at 30 °C with a C tripping curve (magnetic trip between 5× and 10× In, so it handles motor inrush and transformer energisation without nuisance trips) and a 30 mA Type A residual-current element that detects sinusoidal AC and pulsating DC fault currents. Above that, the RCBO derates: 23.5 A at 40 °C, 22.75 A at 45 °C, 21.75 A at 50 °C, 20.25 A at 55 °C and 60 °C, 19.25 A at 65 °C, and 18.25 A at 70 °C. If the panel runs warm — say 50 °C inside a sealed enclosure — you need to size the circuit for 21.75 A continuous, not 25 A. The mounting position is unrestricted, which helps airflow in tight cabinets. Supply can enter from either top or bottom. Halogen-free and silicon-free construction suits environments where outgassing matters, such as clean rooms or food processing areas.","metaTitle":"Siemens 5SU1324-7KX25 SENTRON RCBO, 25A C-curve 30mA Type A","metaDescription":"Siemens 5SU1324-7KX25 SENTRON RCBO, 2-pole, 25A, C-curve, 30mA Type A residual current, 10kA breaking capacity.
