Its 0.3 A rated current with a C tripping characteristic means it is intended for loads with moderate inrush — think control transformers, small contactor coils, or indicator lamp circuits — where the magnetic trip threshold (5–10× In) avoids nuisance trips on startup. The 6 kA breaking capacity is certified to both EN 60898 and IEC 60947-2, so it safely interrupts fault currents up to that level in a 400 V AC system. That dual-standard rating is the key: EN 60898 covers the domestic/infrastructure duty, while IEC 60947-2 confirms the same interrupting rating for industrial panel applications — one part, two compliance paths. The C-curve is the standard choice for general-purpose distribution in European-style panels; it holds through 5× rated current for several seconds before the thermal bimetal trips, then the magnetic trip operates between 5× and 10× In. For a 0.3 A MCB, that means the magnetic pickup is around 1.5–3.0 A — well above the steady-state draw of a small transformer or relay, but fast enough to clear a hard short. This MCB occupies 3 width units on a DIN rail — 54 mm wide — with an installation depth of 70 mm and overall depth of 76 mm. The screw terminals accept solid or stranded conductors from 0.75 to 25 mm², with a tightening torque of 2.5 to 3 N·m. That conductor range covers everything from 1.5 mm² control wiring up to 6 mm² or 10 mm² feeder tails, so it fits standard panel wiring practice without adapters. The product is classified per DIN EN 61346-2 and DIN EN 81346-2 as function code F, which maps to 'protective device' in the standard functional naming scheme.","metaTitle":"Siemens 5SL6314-7 SENTRON MCB, 3P, C-0.3A, 6kA, 400V AC","metaDescription":"Siemens SENTRON 5SL6314-7 miniature circuit breaker, 3-pole, C-curve, 0.3 A, 6 kA per IEC 60898/60947-2, 400 V AC.

It carries a sealable toggle for lockout/tagout, and is rated overvoltage category 3.

However, verify the C-curve and 0.3 A rating match the circuit protection requirements before substituting — a different current rating or tripping characteristic changes the protection coordination."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SL6314-7","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/5SL6314-7 when reusing this data.
