It occupies 3 modular width units (54 mm) on the DIN rail, with a 76 mm depth and 70 mm installation depth behind the panel. The B curve means the magnetic trip activates at 3 to 5 times rated current — suited for resistive and general-purpose loads where inrush is low, like lighting circuits, control transformers, and distribution subfeeds in residential or infrastructure panels. Mounts on standard DIN rail in any position. 3 MW width (54 mm) fits standard distribution board cutout. Pollution degree 2 and overvoltage category III suit fixed-installation panels. 70 mm installation depth leaves clearance for rear-entry wiring.","metaTitle":"Siemens 5SJ6310-6KS SENTRON MCB, 3P, B Curve, 10A, 6kA","metaDescription":"Siemens SENTRON 5SJ6310-6KS miniature circuit breaker, 3-pole, B characteristic, 10A, 6kA breaking capacity per EN 60898/IEC 60947-2, 400V AC.
