The C-curve (trips at 5–10× In) is the go-to for motor and compressor circuits where a brief inrush shouldn't nuisance-trip the RCD side. This is a DIN-rail mount module, 1 module width (18 mm per pole, so 2 modules for the 1P+N form factor). Snaps into any standard TS35 rail inside a consumer unit or sub-distribution board. The neutral connects through the device internally, so no separate neutral bar link needed downstream of this RCBO — it switches and protects both line and neutral.","metaTitle":"Siemens 5SU9356-7CN16 RCBO, 6 kA, 1P+N, Type A, 30 mA, C-Cha","metaDescription":"Siemens 5SU9356-7CN16 RCBO, 6 kA breaking capacity, 1P+N, Type A, 30 mA, C-Characteristic, 16 A rated current, 230 V AC.

Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time."},{"question":"What does the 6 kA breaking capacity mean for my installation?","answer":"The 6 kA Icn rating means this RCBO can safely interrupt a short-circuit fault up to 6,000 A at 230 V AC. It is sized for standard residential and light commercial distribution boards where the prospective short-circuit current at the point of installation does not exceed 6 kA."},{"question":"What is the difference between Type A and Type AC RCDs, and why does this one use Type A?","answer":"Type A RCDs detect pulsating DC residual currents in addition to sinusoidal AC. Type AC only detects pure AC. This 5SU9356-7CN16 is Type A, so it is suitable for circuits with rectified loads like washing machines, LED drivers, and small VFDs that generate pulsating DC fault currents."},{"question":"What compliance documentation does Siemens provide for the 5SU9356-7CN16?","answer":"The standard Siemens RCBO range carries CE marking and is designed to meet IEC/EN 61009-1. RoHS and REACH declarations are typically available in the manufacturer's documentation package. For specific compliance certificates (UL, etc.), check the Siemens Industry Online Support portal for this order code."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SU9356-7CN16","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/5SU9356-7CN16 when reusing this data.
