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.","metaTitle":"SENTRON 5SU1354-7KK08 RCBO, 2-pole, 8 A, C-curve, 10 kA","metaDescription":"SENTRON 5SU1354-7KK08 RCBO, 2-pole, 8 A, C-curve, 10 kA (EN 60898), 20 kA (IEC 60947-2), Type A RCD, 2 MW, halogen-free, current lifecycle.

Verify the fault type your circuit requires before substituting."},{"question":"What are the key dimensions of 5SU1354-7KK08?","answer":"Width 36 mm (2 modular units), height 90 mm, depth 77 mm. Installation depth is 70 mm."},{"question":"Will 5SU1354-7KK08 drop into a panel specified around 5SL4363-7 without rewiring?","answer":"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."},{"question":"What compliance documentation does Siemens provide for 5SU1354-7KK08?","answer":"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.
