The Type C characteristic handles inrush from motor starters and small transformers without nuisance tripping, while the AC-type residual current protection catches sinusoidal faults on standard loads. IP20 rating applies once the board is installed and conductors connected — not for wet environments, but fine inside a dry enclosure. Supply can come from top or bottom, which simplifies busbar routing in a crowded panel. ## Temperature derating you need to know At 40 °C it derates to 23.5 A, at 50 °C to 21.75 A, and at 70 °C to 18.25 A. The unit survives -40 °C storage and operates up to 75 °C ambient, but the trip curve shifts with temperature; the derating table is the safe design reference.","metaTitle":"Siemens 5SU1653-1KK25 SENTRON RCBO, 25 A, Type C, 2-Pole","metaDescription":"Siemens 5SU1653-1KK25 SENTRON RCBO, 25 A rated, Type C trip curve, 2-pole, 4.5 kA (EN 60898) / 15 kA (IEC 60947-2).
