The Siemens 5SU1356-1KV10 is a combination residual current device and miniature circuit breaker — an RCBO in a 1+N-pole form factor. It integrates Type AC residual current protection at 30 mA with a C-curve overcurrent trip set to 10 A, all in a 70 mm wide DIN-rail housing. The 30 mA sensitivity provides residual current protection. The 6 kA breaking capacity handles fault currents in distribution boards.
Panel integration
Snap-on mounting to 35 mm DIN rail per EN 60715. The 70 mm width occupies two standard 17.5 mm module spaces — account for this when planning enclosure fill factor. Bottom terminals accept up to 25 mm² conductors; busbar compatible for feed-through distribution.
