That makes the 5SL4320-0RC the right call for protecting control transformers, PLC power supplies, or DC-side semiconductor bridges where a C-curve might not clear a fault fast enough to avoid device damage. If your panel was originally specced around a 5SL4363-7 (20 A, C-curve, SENTRON), the Z-curve here will trip faster on moderate overloads — verify coordination with downstream loads before swapping.

The key difference: the 5SL4320-0RC uses a Z characteristic (2–3× In), while the 5SL4363-7 uses a C characteristic (5–10× In). Choose the Z-curve when protecting sensitive loads; choose the C-curve for general-purpose distribution. Both share the same 76×54×90 mm footprint, so no panel rework is needed."},{"question":"Can I get pricing and availability for 5SL4320-0RC?","answer":"Pricing and stock are confirmed at quote time against an RFQ. Submit a request through the usual channel; availability is sourced through independent distribution and confirmed on inquiry."},{"question":"What compliance documentation does the 5SL4320-0RC carry?","answer":"The MCB is rated per EN 60898 and IEC 60947-2 for breaking capacity. It is halogen-free and silicon-free. The Betagard series is CE-marked and carries relevant IEC/EN certifications for the European market."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SL4320-0RC","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/5SL4320-0RC when reusing this data.
