Siemens SENTRON 5SU1653-1KK16 — RCBO, 2-Pole, 16 A, Type C, 30 mA AC
It is rated 16 A at 30 °C with a Type C tripping characteristic (5–10× In for motor and lighting inrush) and 30 mA AC residual current sensitivity for personnel and fire protection. The breaking capacity is 4.5 kA per EN 60898 and 15 kA per IEC 60947-2, giving it headroom for industrial panel coordination where the upstream device clears higher faults.
Thermal derating and mounting flexibility
At 40 °C it derates to 15.2 A, at 50 °C to 14.4 A, and at 70 °C to 12.32 A — a continuous curve that matters when the RCBO shares a crowded enclosure with other heat sources.
Touch protection is provided on the terminals. The product designation per IEC 81346-2 and DIN EN 61346-2 is F (protective device).
