Product details

It combines overcurrent protection and Type A residual current detection in a single 2-module-width (36 mm) package — a space-saving fit for DIN-rail distribution boards where separate MCB+RCCD won't fit.

Derating and mounting

The 8 A rating holds at 30 °C; at 40 °C it derates to 7.52 A, and at 50 °C to 6.96 A. At 70 °C the continuous rating drops to 5.84 A. The IP20 rating applies only when the distribution board is installed with conductors connected — bare terminals are not finger-safe outside the enclosure.

Halogen-free and silicon-free construction meets clean-material requirements for sensitive environments like data centers or medical facilities.

Frequently asked questions

What is the closest functional second-source to 5SU1354-7KK08?

The 5SL4363-7 is a 2-pole RCBO from the same SENTRON family with similar ratings, but it uses a different residual current characteristic (Type AC vs Type A). Verify the fault type your circuit requires before substituting.

What are the key dimensions of 5SU1354-7KK08?

Width 36 mm (2 modular units), height 90 mm, depth 77 mm. Installation depth is 70 mm.

Will 5SU1354-7KK08 drop into a panel specified around 5SL4363-7 without rewiring?

The 5SU1354-7KK08 and 5SL4363-7 share the same 2-module-width footprint and DIN-rail mounting, so mechanical fit is the same. However, the 5SU1354-7KK08 is Type A residual current, while the 5SL4363-7 is Type AC — the wiring is identical, but the protection characteristic differs. No rewiring needed, but verify the RCD type matches your load.

What compliance documentation does Siemens provide for 5SU1354-7KK08?

The part is designed to EN 60898 and IEC 60947-2, and carries a CE mark for the European market. It is halogen-free and silicon-free. Specific declarations (RoHS, REACH) are available from Siemens on request.
