If your panel ambient runs above 40 °C, the effective current capacity drops — size the upstream feeder accordingly. The C-curve means magnetic trip between 5× and 10× In, so it handles moderate inrush from motor starters or transformers without nuisance tripping, but still clears a hard fault fast. Breaking capacity is 6 kA per EN 60898 and 10 kA per IEC 60947-2. That 10 kA figure is the one that matters for industrial panels with higher fault current potential — it safely interrupts a fault up to 10 kA at the rated voltage without cascading upstream. The 30 mA residual-current element provides personnel protection (shock hazard) and fire protection for low-level earth faults. Temperature range of -40 to 75 °C covers unheated outdoor cabinets and hot machine compartments — no up-tower swaps needed for a nacelle environment. The part is halogen-free and silicon-free, which matters for clean-room or sensitive electronics zones where outgassing can corrode contacts. ## Panel integration notes Mounts on DIN rail in any position. Depth is 77 mm, installation depth 70 mm — verify the enclosure door clearance if using a deep cover. The 36 mm width (2 MW) fits standard modular grids. Supply can enter from top or bottom. Touch protection is built in.","metaTitle":"Siemens 5SU9356-1CR32 SENTRON RCBO, 32 A, 30 mA, C-curve","metaDescription":"Siemens SENTRON 5SU9356-1CR32 RCBO, 2-pole, 32 A, 30 mA, type AC, C-curve, 6/10 kA breaking capacity, -40 to 75 °C.
