Rated at 25 A and 230/240 V AC, 50 Hz, it delivers a breaking capacity of 10 kA per EN 60898 and 20 kA per IEC 60947-2, giving headroom for fault currents in standard commercial and industrial distribution boards. The 1P+N configuration switches the phase and switches the neutral, with the neutral conductor switching function confirmed. ## Panel Integration & Mounting Breaking capacity of 10 kA (EN 60898) and 20 kA (IEC 60947-2) covers most building and industrial distribution scenarios; the higher IEC rating applies when the RCBO is used as a circuit breaker per IEC 60947-2, giving additional fault-current headroom. Touch protection is integrated, and the design is instantaneous (no intentional time delay on the residual side).","metaTitle":"Siemens 5SU1454-1KK25 SENTRON RCBO, 25A, 100mA, Type AC, 10k","metaDescription":"Siemens 5SU1454-1KK25 SENTRON RCBO, 2-pole, 25 A, 100 mA residual, Type AC, 10 kA (EN 60898) / 20 kA (IEC 60947-2), 230/240 V AC.
