Product details

It protects a single-phase final subcircuit against both overload/short-circuit and earth leakage in one device, saving a DIN-rail position compared to a separate MCB + RCCB pair. 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.

Frequently asked questions

Will 5SU1653-1KK06 drop into a panel that was specified around 5SU9354-7KK16 without rewiring?

Both are 2-module-wide (36 mm) SENTRON RCBOs on the same DIN-rail footprint, so the mechanical fit is identical. The key difference is the residual-current rating: 5SU1653-1KK06 trips at 300 mA, while 5SU9354-7KK16 trips at a different threshold. Verify the circuit's required earth-leakage protection level before swapping.
