The interrupting capacity is 10 kA per EN 60898 and 15 kA per IEC 60947-2, giving it solid fault-clearing headroom for most commercial and light-industrial distribution boards. The 40 A rating holds at 30 °C ambient; at 40 °C it derates to 37.6 A, and at 50 °C to 34.8 A — so if the panel runs hot, size up or verify the actual load stays under the derated curve. Type F residual current detection covers sinusoidal AC, pulsating DC, and mixed-frequency faults up to 1 kHz — exactly what you get from a VFD-fed load or a washing machine inverter. The 10/15 kA SCCR means it safely interrupts faults up to that level without welding contacts or cascading upstream; that's enough for a typical sub-distribution board fed by a 100–200 A transformer. Snaps onto standard 35 mm DIN rail, occupies 2 modular units (36 mm wide). The supply can enter from either top or bottom — no forced orientation. Mounting position is any orientation.","metaTitle":"Siemens 5SU1354-3KK40 SENTRON RCBO, 2-pole 40A Type F, 10kA","metaDescription":"Siemens 5SU1354-3KK40 SENTRON RCBO, 2-pole 1P+N, 40A rated, Type F residual current, 10kA (EN 60898) / 15kA (IEC 60947-2).

The 5SU1354-3KK40 is an RCBO that combines overcurrent and earth-leakage protection in one unit.
