The 25 A rating at 30 °C drops to 18.25 A at 70 °C — a 27 % derating. Operating frequency is 50 Hz only — not 50/60 Hz dual-rated. If the installation is on a 60 Hz supply, this part does not apply. Depth is 77 mm, installation depth 70 mm.","metaTitle":"Siemens 5SU1353-7KK25 SENTRON RCBO, 25 A, Type C, 2-pole","metaDescription":"Siemens SENTRON 5SU1353-7KK25 RCBO, 1P+N, 25 A at 30 °C, Type C tripping, 4.5 kA (EN 60898) / 15 kA (IEC 60947-2).
