Frequently asked questions

What is 5SV3644-6KK12's listed depth (70 mm) on this component line?

Depth is 70 mm, installation depth also 70 mm.

What is 5SV3644-6KK12's listed width (72 mm) on this component line?

Width is 72 mm, corresponding to 4 modular width units.

Will 5SV3644-6KK12 drop into a panel that was specified around 5SY4350-5 without rewiring?

No. Both mount on DIN rail, but the 5SV3644-6KK12 is a 4-pole RCCB requiring different circuit connections and terminal arrangement. Rewiring is necessary.
