The 25 A rating at 30 °C is the headline number, but the derating curve is what a panel builder needs: at 40 °C it's 23.5 A, at 50 °C it's 21.75 A, and at 70 °C it drops to 18.25 A. If your enclosure runs hot, size the branch circuit accordingly. The C-curve means magnetic trip occurs at 5–10× In, typical for motor and lighting loads with moderate inrush. The installation depth is 70 mm, with an overall depth of 77 mm including the front face. ## Integration notes The insulation voltage (Ui) is 264 V, and surge voltage resistance is 4 kV.","metaTitle":"Siemens 5SU1356-7KK25 SENTRON RCBO, 25 A, C-curve, 2-pole","metaDescription":"Siemens 5SU1356-7KK25 SENTRON RCBO, 25 A rated at 30 °C, C tripping characteristic, 2-pole (1P+N), 6 kA per EN 60898, 15 kA per IEC 60947-2.
