Its 6 kA breaking capacity is certified under both EN 60898 and IEC 60947-2, meaning it safely clears fault currents up to that level in residential and infrastructure distribution boards. The C-curve (5–10× In) handles moderate inrush from motor starters and lighting ballasts without nuisance tripping — a common choice for general-purpose branch circuits. ## Dimensions and mounting Occupies 3 modular width units (54 mm) on a DIN rail, with a depth of 76 mm and an installation depth of 70 mm. Mounting position is unrestricted, and the IP20 rating (with connected conductors) is standard for enclosed panel environments. The housing is halogen-free and silicon-free — relevant for installations where outgassing must be minimized, such as in clean rooms or near sensitive contacts. ## Environmental range and accessories Rated for ambient temperatures from -40 °C to 75 °C, covering most indoor and sheltered outdoor enclosures. The breaker accepts supplementary devices (auxiliary switches, shunt trips, alarm contacts) for remote status or emergency-off integration. The enclosure is sealable, which helps prevent tampering in accessible locations.","metaTitle":"Siemens 5SL6306-7 SENTRON MCB, 3P C 6A, 6 kA","metaDescription":"Siemens 5SL6306-7 SENTRON miniature circuit breaker, 3-pole, C-curve, 6 A, 400 V AC, 6 kA breaking capacity per EN 60898 & IEC 60947-2.

The 5SL4363-7 has a 10 kA breaking capacity versus 6 kA on the 5SL6306-7. They are mechanically interchangeable — same footprint, same mounting — but the interrupting rating must match the available fault current at the panel."},{"question":"Will 5SL6306-7 drop into a panel specified around 5SL4363-7 without rewiring?","answer":"Yes, the 5SL6306-7 shares the same 54 mm width, 76 mm depth, and DIN-rail mounting as the 5SL4363-7. No rewiring or busbar change is needed — the only difference is the 6 kA versus 10 kA interrupting rating, so confirm the available fault current at the installation point first."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SL6306-7","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/5SL6306-7 when reusing this data.
