That 15 kA IEC rating is the one that governs industrial panel coordination: it tells you this MCB can clear a fault up to 15 kA without welding its contacts or venting arc gas into the enclosure, which matters when you're sizing the upstream backup fuse or breaker. ## What the ratings mean for fit C-curve trips between 5× and 10× In — standard for motor-starting and moderate inductive loads where you need inrush headroom without nuisance tripping. At 18 mm width (1 modular unit), it snaps onto standard DIN rail and occupies one slot in any SENTRON distribution board or industrial panel. Pollution degree 3 and overvoltage category 3 mean it's rated for the conductive-dust and transient environment you get in a real factory panel, not just a clean residential loadcenter.","metaTitle":"Siemens 5SJ4113-7HG42 SENTRON MCB, 1P C-curve, 10kA","metaDescription":"Siemens 5SJ4113-7HG42 SENTRON miniature circuit breaker, 1-pole, C-curve, 10 kA per EN 60898, 15 kA per IEC 60947-2, 400 V AC, 18 mm wide, current production.

The IEC 60947-2 figure is the one to use for industrial panel coordination as it reflects the higher test duty cycle."},{"question":"What is the physical size — will it fit a standard DIN-rail panel?","answer":"18 mm wide (1 modular unit), 121 mm tall, 70 mm deep. It clips onto standard 35 mm DIN rail and occupies one slot. Depth of 70 mm is the installed depth including terminals, so check your enclosure depth against that figure."},{"question":"What approvals or compliance documentation does this carry?","answer":"The 5SJ4113-7HG42 is rated per EN 60898 and IEC 60947-2. It is halogen-free and silicon-free. The SENTRON series carries CE marking and is UL/CSA recognized through Siemens' global certification. Specific RoHS/REACH declarations are available from Siemens' documentation portal for this order code."},{"question":"How does the 5SJ4113-7HG42 compare to the 5SL4363-7?","answer":"The 5SL4363-7 is a different Siemens MCB series (5SL vs 5SJ4) with different breaking capacity ratings and terminal design. The 5SJ4113-7HG42 uses combined top/bottom terminals and is rated for 15 kA per IEC 60947-2; the 5SL series typically has lower interrupting ratings. They are not direct drop-in replacements — verify the interrupting capacity requirement and terminal type before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SJ4113-7HG42","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/5SJ4113-7HG42 when reusing this data.
