Rated 6 A at AC with C characteristic. 300 mA residual-current element is type AC. The instantaneous design means no intentional time delay on the residual-current trip — it clears a ground fault within the standard IEC 61008 cycle. ## Integration into the panel Snaps onto standard DIN rail. Depth 77 mm (70 mm installation depth). Width 36 mm occupies two modular slots. Supply can enter from top or bottom, which simplifies wiring in pre-bussed panels. IP20 rating applies once the distribution board is installed with conductors connected — the device itself is not sealed against dust ingress beyond finger-safe touch protection. Above that, derate linearly: 5.7 A at 40 °C, 5.58 A at 45 °C, 5.4 A at 50 °C, 5.22 A at 55 °C, 5.1 A at 60 °C, and 4.86 A at 65 °C, down to 4.62 A at 70 °C.","metaTitle":"Siemens SENTRON 5SU1653-1KK06 RCBO, 6 A, C-Curve, 300 mA, 2-","metaDescription":"Siemens SENTRON 5SU1653-1KK06 RCBO, 6 A rated, C tripping characteristic, 300 mA residual current, 4.5 kA breaking capacity.
