The C-curve means the magnetic trip fires at 5 to 10 times rated current — 50 to 100 A for this 10 A breaker. That suits motor-starting or transformer inrush where a B-curve would nuisance-trip. The 6 kA breaking capacity is the same under both the wiring-standard (EN 60898) and industrial (IEC 60947-2) test sequences; if your panel SCCR is higher, you need an upstream current-limiting device. The screwless outgoing terminals accept ferruled stranded or solid conductors — speeds up panel wiring vs screw-clamp, but verify the strip length against the terminal design if your shop is used to a different brand's cage clamp. ## Environmental and mounting notes Rated for any mounting position, so it works in horizontal busbar panels or vertical DIN-rail cabinets without derating.","metaTitle":"Siemens 5SJ6310-7KS SENTRON MCB, 3P C 10A 6kA, 400V","metaDescription":"Siemens 5SJ6310-7KS SENTRON miniature circuit breaker, 3-pole, C-curve, 10A, 6kA breaking capacity per IEC 60898 and IEC 60947-2, 400V AC.
