If your panel was originally specified with a 5SL3625-7MB (C-curve, 25 A), swapping to this D-curve unit means you gain inrush headroom but lose faster trip on lower-level faults; the physical footprint (3 width units, 54 mm wide) and terminal range (0.75–25 mm² solid/stranded) are identical, so no rewiring needed. Screw terminals accept 0.75–25 mm² solid or stranded copper; torque to 2.5–3 N·m. Rated for ambient -25 to +45 °C operating, -40 to +75 °C storage. Halogen-free and silicon-free construction.","metaTitle":"Siemens 5SN6325-8CN SENTRON MCB, 3P D 25A 6kA 400V","metaDescription":"Siemens 5SN6325-8CN SENTRON miniature circuit breaker, 3-pole, D-curve, 25 A, 6 kA per EN 60898, 400 V AC.
