The C curve means it tolerates brief inrush currents 5 to 10 times the rated current — standard for mixed resistive and light inductive loads like lighting circuits, small transformers, and general socket outlets in residential or light commercial distribution boards. The 7.5 kA short-circuit capacity is the maximum fault current it can safely interrupt at the rated voltage; for panels fed by a transformer with higher prospective fault current, you'd need a current-limiting upstream device or a breaker with a higher kA rating. ## Integration and panel fit Occupies 3 modular width units (54 mm total) on a DIN rail, with a depth of 76 mm and an installation depth of 70 mm. Mounting position is any — no derating required for upside-down or sideways installation in a tight enclosure. IP20 with connected conductors, so it's protected against finger contact but not washdown; install inside a distribution board or enclosure rated for the environment. Sealable, halogen-free, and silicon-free — important for environments where outgassing or silicone contamination matters (e.g., near sensitive contacts or in clean-ish industrial zones).","metaTitle":"Siemens 5SL6306-7RC SENTRON MCB 6A 3P C 7.5kA","metaDescription":"Siemens 5SL6306-7RC SENTRON MCB, 6A, 3-pole, C characteristic, 7.5kA breaking capacity per EN 60898.

Submit a request for quote to confirm availability and current pricing."},{"question":"When sourcing 5SL6306-7RC, what's the closest functional alternative — 5SL4363-7?","answer":"The 5SL4363-7 is a close sibling: same 3-pole C-curve, same 6 A rating, same mechanical footprint (76 mm depth, 54 mm width, 3 MW). The key difference is breaking capacity — the 5SL4363-7 is rated 10 kA per both EN 60898 and IEC 60947-2, versus 7.5 kA for the 5SL6306-7RC. It also carries an Energy Limitation Class of 3 (the 5SL6306-7RC does not list one), and its per-pole power loss at rated current is higher at 5 W versus 0.86 W. Panel cutout and wiring are identical, but the 5SL4363-7 runs hotter and requires a higher fault-current rating upstream."},{"question":"Will 5SL6306-7RC drop into a panel that was specified around 5SL4363-7 without rewiring?","answer":"Yes, the physical dimensions are identical: same 76 mm depth, 54 mm width, 70 mm installation depth, and 3 modular width units. DIN-rail clip and terminal layout match. No rewiring needed for the swap, but verify the panel's prospective short-circuit current does not exceed 7.5 kA at 415 V — the 5SL4363-7 was rated for 10 kA, so the 5SL6306-7RC has less headroom."},{"question":"What compliance documentation does Siemens provide for 5SL6306-7RC?","answer":"The 5SL6306-7RC is halogen-free and silicon-free, which supports RoHS and REACH compliance. The IP20 rating and Overvoltage Category III indicate it meets IEC 60947-2 and EN 60898 construction standards. Declaration of conformity and CE marking documentation are available through Siemens channels."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SL6306-7RC","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/5SL6306-7RC when reusing this data.
