The 5SL6225-7BB: This Italy-spec version (catalog suffix -7BB) is built for residential buildings and infrastructure duty. The C-curve means it trips between 5× and 10× rated current — standard for mixed resistive and moderate inductive loads like lighting circuits, general-purpose outlets, and small motor branch circuits where inrush isn't extreme.
Mounting and integration
Occupies 2 modular width units (36 mm) on a standard DIN rail. Depth is 76 mm (70 mm installation depth behind the panel surface). Mounting position is unrestricted — any orientation works. IP20 protection with connected conductors, so it belongs in an enclosed distribution board or panel, not out in the weather. Sealable design for tamper-proof installations. Halogen-free and silicon-free construction matters if this goes into a panel serving sensitive electronics or a clean environment — no corrosive off-gassing during a fault.
Thermal derating and service life
Rated 25 A at 30 °C ambient. At 40 °C it derates to 23.68 A; at 45 °C to 23 A; at 55 °C to 21.54 A. If your panel runs hot — say a packed enclosure near a boiler or drive — factor that reduction into your load schedule. Mechanical service life is 10 000 switching cycles typical, which is standard for a DIN-rail MCB in a distribution board that sees infrequent manual operation.
Sourcing and lifecycle
Current production — no EOL or LTB signal on this order code. Sourced to order through independent distribution; availability and current pricing confirmed at quote time against an RFQ. No official successor because none is needed yet.
