The 30 mA Type AC residual sensitivity catches sinusoidal AC earth faults; it is the baseline choice for most residential and commercial circuits, not for pulsed DC or smooth DC fault types. The 20 A rating on a 2-pole 1P+N design switches the live conductor and switches the neutral, so it fits single-phase circuits where neutral isolation is required. ## Integration — DIN-rail fit and panel considerations The 2-module width (36 mm) occupies the same slot count as a standard 2-pole MCB. IP20 protection applies once the distribution board is installed with conductors connected — the RCBO itself is not sealed against washdown. Humidity tolerance up to 95% non-condensing.","metaTitle":"Siemens 5SU1354-1RC20 SENTRON RCBO, 20 A, C-curve, 30 mA, 2-","metaDescription":"Siemens SENTRON 5SU1354-1RC20 RCBO, 20 A rated, C characteristic, 30 mA Type AC, 10 kA (EN 60898) / 20 kA (IEC 60947-2), 2-pole 2-module.

Both share the same 2-module width (36 mm), 90 mm height, and DIN-rail mounting, so the physical footprint is identical. However, the 5SU1354-1RC20 requires a neutral connection for the residual current electronics and has a lower current rating — it is not a direct functional replacement for a 50 A MCB."},{"question":"What compliance documentation is available for 5SU1354-1RC20?","answer":"The part carries ratings per EN 60898 (10 kA) and IEC 60947-2 (20 kA), which are the relevant product standards for RCBOs.
