The Siemens SENTRON 5SU1353-1WM16 is a 1P+N RCBO combining overcurrent and residual current protection in a two-module-width package. Rated 16 A with a C tripping curve, it clears 30 mA AC fault currents (Type AC) per EN 60898 at 4.5 kA and per IEC 60947-2 at 15 kA — the higher IEC figure matters when the device sits in an industrial panel with higher prospective fault current, while the EN rating governs residential and commercial distribution boards. The 30 mA trip threshold is the standard for personal protection against indirect contact in TN and TT systems.
The 30 mA residual sensitivity covers the majority of socket-outlet and general-purpose circuits requiring RCD protection under IEC 60364. The 4.5 kA EN 60898 rating is the standard domestic/commercial breaking capacity; the 15 kA IEC 60947-2 rating confirms the device can also clear higher fault currents found in industrial sub-distribution boards.
