It is a 3-pole unit rated 1.6 A at 400 V AC with a D tripping characteristic and a 6 kA breaking capacity per EN 60898. The D-curve means this breaker is sized for loads with high inrush current — typically motor starters, small transformers, or discharge lighting — where the magnetic trip threshold is 10 to 20 times the rated current. At 1.6 A, the magnetic release will hold through a starting surge up to roughly 16–32 A before clearing a hard fault. The 6 kA breaking capacity (per EN 60898) tells you it can safely interrupt a fault current up to 6 kA at 400 V AC without welding contacts or cascading failure upstream. That is the standard domestic and light-commercial SCCR level for this class; if your available fault current exceeds 6 kA, you need a current-limiting upstream device or a higher-rated breaker. Three poles (3P) with no switched neutral — the neutral conductor passes through unswitched, which is standard for TN and TT systems where the neutral is bonded at the source. The 3 width units (54 mm) on DIN rail are what you plan for in the enclosure layout. ## Mounting and wiring constraints Mounts on 35 mm DIN rail in any position. The 76 mm depth and 70 mm installation depth fit standard distribution boards; verify door clearance if using a deep enclosure lid. Terminals accept solid or stranded copper from 0.75 mm² up to 25 mm². Tightening torque is 2.5 to 3 N·m — a standard screwdriver bit, no special tooling. The IP20 rating applies with conductors connected; the enclosure must provide the overall panel IP rating. Sealable design (provision for a lead seal or lockout tag) is present, which matters for installations requiring tamper evidence per local utility or safety rules.","metaTitle":"Siemens 5SL6315-8CC SENTRON MCB, 3P D 1.6A 6kA","metaDescription":"Siemens 5SL6315-8CC SENTRON miniature circuit breaker, 3-pole, D-curve, 1.6 A, 6 kA per EN 60898, 400 V AC.
