Product details

That 10 kA SCCR covers the vast majority of final-subcircuit fault levels in commercial and light-industrial distribution boards; the type A detection handles pulsating DC fault currents from electronics and single-phase rectifiers, which a plain AC-sensitive RCD would miss. At 30 °C ambient the unit carries its full 10 A rating. Above that, derate linearly: 9.4 A at 40 °C, 9.1 A at 45 °C, 8.7 A at 50 °C, and 8.1 A at 55 °C. If the panel runs warm — common in a crowded enclosure — factor that thermal curve into the load calculation rather than relying on the 30 °C number alone. Mounting position is unrestricted, and the supply cord can enter from either top or bottom. IP20 rating applies once the distribution board is installed with conductors connected — normal for a panelboard device, not for exposed outdoor use.

Halogen-free and silicon-free construction. Overvoltage category III, pollution degree 2, insulation voltage rated 264 V, surge voltage resistance 4 000 V.

Frequently asked questions

What is the depth of 5SU9654-7KK10?

Listed depth is 77 mm, with an installation depth of 70 mm.

What is the width of 5SU9654-7KK10?

Width is 36 mm, which corresponds to 2 modular width units on a standard DIN rail.

Will 5SU9654-7KK10 drop into a panel specified around 5SY7210-7CC without rewiring?

Both are 2-module-width DIN-rail devices, so the mechanical fit is the same. However, the 5SU9654-7KK10 is an RCBO (overcurrent + residual current combined) while the 5SY7210-7CC is a plain MCB — the wiring and circuit protection scheme differ. A direct swap without verifying the circuit's protection requirements is not recommended.
