It is rated 63 A at 230/240 V AC, 50/60 Hz, with a 30 mA residual current trip — the standard threshold for personal protection against electric shock in final circuits. The 1 kA surge current withstand (8/20 μs waveform) gives it basic immunity to lightning-induced transients on the line side. The 77 mm depth (70 mm installation depth) fits flush in most distribution boards without protruding beyond the enclosure depth. Supply can enter from top or bottom — no mandatory orientation. Touch protection is built in (fingertip-safe terminals per IP20 when the board is closed with conductors connected). The neutral conductor is switched internally (1P+N), so no separate neutral bar connection is needed downstream of this device. Halogen-free and silicon-free construction. Overvoltage category III, pollution degree 2 — suitable for fixed installations downstream of the utility meter. The device is classified as energy limitation class 3, meaning it limits let-through energy in a fault to a level that protects downstream wiring.","metaTitle":"Siemens 5SU9356-1CR63 SENTRON RCBO, 63 A, 30 mA, C-curve","metaDescription":"Siemens 5SU9356-1CR63 SENTRON RCD-operated circuit breaker, 63 A rated, 30 mA residual current, C-curve, 6/10 kA breaking capacity.

Availability and current pricing are confirmed at quote time."},{"question":"What is the closest functional second-source to 5SU9356-1CR63?","answer":"The closest functional peer in the SENTRON family is the 5SL6550-7BB, which is also a 1P+N RCBO but rated 50 A instead of 63 A. The 5SU9356-1CR63 carries a higher continuous current rating, so a direct drop-in replacement without rewiring is only possible if the circuit load does not exceed 50 A. The 5SY5250-7 and 5SY5240-7 are MCBs only (no RCD function) and are not functional substitutes."},{"question":"What is 5SU9356-1CR63's listed depth (77 mm) on this component line?","answer":"The depth is 77 mm, with an installation depth of 70 mm (the difference accounts for the front face and terminal protrusion)."},{"question":"What is 5SU9356-1CR63's listed width (36 mm) on this component line?","answer":"The width is 36 mm, which corresponds to 2 modular width units (MW) on a standard DIN rail."},{"question":"Will 5SU9356-1CR63 drop into a panel that was specified around 5SL6550-7BB without rewiring?","answer":"Yes, the 5SU9356-1CR63 shares the same 1P+N pole configuration, 36 mm width, and DIN-rail mounting as the 5SL6550-7BB, so it fits the same physical footprint and wiring arrangement. The only difference is the 63 A rating versus 50 A — verify the circuit's overcurrent protection requirements before substituting."},{"question":"What compliance documentation does this brand provide for 5SU9356-1CR63 (RoHS, REACH, UL, IEC)?","answer":"The device is designed and tested to EN 60898 and IEC 60947-2, as indicated by its dual breaking capacity ratings. It carries an IP20 protection class (with distribution board installed). Halogen-free and silicon-free construction is confirmed. The evidence does not list specific RoHS, REACH, or UL certifications, but these are standard for SENTRON products sold in the EU market."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SU9356-1CR63","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/5SU9356-1CR63 when reusing this data.
