The Siemens SENTRON 5SL6325-7YA is a 3-pole miniature circuit breaker (MCB) with a C-trip curve, rated at 25 A and 400 V AC. It provides a 6 kA breaking capacity in accordance with EN 60898, making it suitable for protecting branch circuits in residential and infrastructure panels against overloads and short circuits. The C-curve characteristic means it trips at 5 to 10 times the rated current — standard for inductive and motor-starting loads where inrush is moderate. At 25 A and 400 V, this covers typical lighting, socket-outlet, and small-motor circuits in a 3-phase distribution board. Mechanical life is rated at 10,000 operating cycles typical. The breaker is sealable, halogen-free, and silicon-free, with a degree of pollution 2 and overvoltage category III rating.
Panel fit and integration
The 5SL6325-7YA occupies 3 modular width units (54 mm total) on a standard DIN rail. Depth is 76 mm, installation depth 70 mm. Mounting position is any, and the IP20 rating applies with the distribution board cover fitted. No supplementary devices (auxiliary switches, shunt trips, undervoltage releases) can be installed on this variant — the product extension is marked as not installable. If add-on accessories are needed, the 5SL4363-7 series supports them.
Lifecycle and sourcing
The 5SL6325-7YA is in active current production. It is sourced and quoted to order through independent distribution; availability and current pricing are confirmed at quote time against an RFQ.
