Type F means it detects AC pulsating and smooth DC fault currents plus high-frequency residuals from variable-speed drives and LED lighting, which standard Type A devices miss. Supply can land on either top or bottom terminals, and the unit mounts in any position inside an IP20 enclosure. In a typical 40 °C panel, the continuous current drops to 30.4 A; at 50 °C it's 28.8 A; at 55 °C (the upper operating limit) it's 27.84 A. The maximum power dissipation is 11.4 W, which adds to the enclosure's thermal budget. That top end (35 mm²) is oversized for a 32 A device — it allows looping through or tapping a larger feeder without a separate terminal block.","metaTitle":"Siemens 5SU1354-3KK32 SENTRON RCBO, 32 A, Type F, 10 kA, 2-p","metaDescription":"Siemens SENTRON 5SU1354-3KK32 RCBO, 32 A rated, Type F fault current, B curve, 10 kA breaking capacity (EN 60898).
