That 6 kA figure applies per both EN 60898 and IEC 60947-2, so it's certified for residential and light commercial distribution boards where the prospective short-circuit current stays under that threshold. The C-curve means it trips between 5 and 10 times rated current — standard for general-purpose loads like lighting, socket circuits, and small appliances where you don't want nuisance trips from inrush but still need fast clearing on a hard fault. At 36 mm wide (2 modular width units), it snaps onto a standard DIN rail and occupies two slots in a distribution board. The 76 mm depth and 70 mm installation depth keep it flush with other SENTRON 5SL series breakers, so it fits existing enclosures without re-spacing. Mounting position is any — no derating needed for horizontal or inverted orientation, which simplifies panel layout. Power loss per pole is 2.6 W at rated current in hot operating state — useful to know for thermal budgeting inside a sealed enclosure. The breaker is sealable (tamper-evident cover available), halogen-free and silicon-free, which matters for installations with sensitive contacts or where off-gassing during a fault must be minimized. ## Where it fits in the panel Rated for overvoltage category III and pollution degree 2 — that's the standard for fixed-installation distribution boards inside a building envelope. The IP20 rating (with connected conductors) means it's protected against finger contact but not against water ingress; it belongs inside a cabinet, not in a washdown zone. Operating temperature range is -40 °C to 75 °C, so it handles unheated utility rooms or outdoor enclosures in temperate climates.","metaTitle":"Siemens 5SL6225-7 SENTRON MCB, 2P C 25A 6kA","metaDescription":"Siemens 5SL6225-7 SENTRON miniature circuit breaker, 2-pole, C-curve, 25 A, 6 kA breaking capacity per IEC 60898/60947-2.
