The Siemens 5SU9353-7CN06 is a 1P+N RCBO rated 6 A with a C-trip curve and 30 mA Type A residual current protection, breaking capacity Icn 4.5 kA at 230 V AC. The C-curve means it trips between 5 and 10 times rated current — sized for mixed resistive and moderate inductive loads like small motors or lighting circuits where inrush isn't extreme. Type A detection catches pulsating DC fault currents from rectified loads (switched-mode supplies, variable-speed drives), which standard AC-only RCDs miss. The 30 mA sensitivity covers personnel protection in wet or outdoor sub-circuits per IEC 60364.
Panel integration
Snaps onto standard DIN rail in a consumer unit or sub-distribution board. 1P+N form factor occupies a single module width — keeps panel density tight. Rated for 230 V AC line-to-neutral circuits; verify the neutral bar arrangement in the enclosure matches the integrated neutral switching.
