That means a single device protects a final circuit against both overload/short-circuit and earth leakage, saving a DIN-rail position versus separate MCB + RCCD. Rated 32 A at 30 °C ambient, with a derating curve published down to 24.64 A at 70 °C. If your enclosure runs hot (say 50 °C), plan for 28.8 A continuous — the 32 A label only holds at 30 °C. If your fault level at the panel exceeds 10 kA, you need an upstream current-limiting device or a higher-rated breaker. The residual current module detects AC-type earth leakage only. If your load generates pulsed DC fault currents (variable-speed drives, LED drivers, UPS equipment), specify an A- or F-type RCBO instead — the 5SU1 AC type will not trip on smooth DC or mixed-frequency waveforms. Width is 36 mm (2 module units). Accepts solid or stranded conductors from 0.75 mm² up to 35 mm² — covers everything from 1.5 mm² lighting circuits to 10 mm² sub-mains. Supply can enter from top or bottom, which simplifies busbar routing in dense panels. Installation depth is 70 mm (device body 77 mm overall). IP20 rating applies only when the distribution board is installed and conductors are connected — the terminals are finger-safe but the device is not sealed against dust ingress. In a multi-device enclosure, sum the losses and check the cabinet's thermal dissipation — 12 RCBOs at full load would dump nearly 140 W inside the panel.","metaTitle":"Siemens 5SU1654-1KK32 SENTRON RCBO, 32 A, C-curve, 10 kA, 2-","metaDescription":"Siemens 5SU1654-1KK32 SENTRON RCBO, 32 A rated, C tripping curve, 10 kA breaking capacity (EN 60898), 2-pole 1P+N, AC fault current, IP20.
