Breaking capacity is rated at 10 kA according to EN 60898 and 15 kA per IEC 60947-2 at 400 V AC. Rated voltage is 400 V AC (phase-to-phase on a 3-phase 4-wire system) and 60 V DC maximum. The DC rating is limited to 60 V because the single-break contact design cannot reliably extinguish a DC arc at higher voltages — specify a DC-rated MCB if the circuit exceeds 60 V DC. Halogen-free and silicon-free construction, suitable for environments where outgassing from a fault could contaminate sensitive equipment or where silicone contamination affects downstream processes like paint adhesion or semiconductor fab. Vibration resistance tested at 50 m/s² over 25 to 150 Hz and 60 m/s² at 35 Hz (4-second dwell) — sufficient for mounting on machine frames or conveyor sections without additional damping. Lifecycle status is current production. This is an active catalog line from Siemens SENTRON — no end-of-life notification or last-time-buy window has been issued.","metaTitle":"Siemens 5SJ4230-7HG41 SENTRON MCB, 2P C-Curve, 10kA/15kA","metaDescription":"Siemens 5SJ4230-7HG41 SENTRON 2-pole miniature circuit breaker, C characteristic, 10 kA (EN 60898) / 15 kA (IEC 60947-2) breaking capacity.

The 5SJ4230-7HG41 carries a higher IEC breaking capacity (15 kA vs the 5SY7206-7CC's typical 10 kA), so verify the fault level at the installation point before substituting — the 5SY series is the economy line, while the 5SJ4 series is the industrial-duty variant."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SJ4230-7HG41","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/5SJ4230-7HG41 when reusing this data.
