That dual rating is important — EN 60898 is the residential/commercial standard (lower internal arc resistance), while IEC 60947-2 is the industrial standard (higher arc resistance, tested at power factor typical of industrial networks). The C-curve (magnetic trip at 5–10× rated current) is the default for motor branch circuits and mixed loads — it rides through the 8–10× FLA inrush of a standard induction motor starting across the line. Power loss per pole: 4.2 W at rated current. Width: 18 mm per pole (3 modular units total). Height: 90 mm. Mounting position: any — vertical, horizontal, upside-down. The thermal-magnetic mechanism is orientation-independent, so no derating needed for side-mount or inverted installation. Vibration-resistant per IEC 60068-2-6, which covers the typical 2–9 Hz and 10–150 Hz sweep found on conveyor drives and compressor skids.","metaTitle":"Siemens Betagard 5SL7350-7RC MCB, 3-pole C-curve 15 kA 415 V","metaDescription":"Siemens Betagard 5SL7350-7RC miniature circuit breaker, 3-pole, C-curve, 15 kA breaking capacity at 415 V AC.

It's 54 mm wide (same 3-module footprint) and shares the same 76 mm depth, so it drops into the same DIN-rail slot. The Betagard carries a higher interrupting rating for industrial fault levels; the SENTRON is rated for residential/infrastructure duty. If your panel requires 15 kA at 415 V, the 5SL7350-7RC is the correct part — the 5SL4363-7 would be undersized."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SL7350-7RC","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/5SL7350-7RC when reusing this data.
