What this MCB does on the line
The Siemens 5SL4125-7CC is a 1-pole miniature circuit breaker from the SENTRON 5SL4 series, rated 25 A with a C tripping characteristic and a 10 kA breaking capacity per EN 60898. It protects branch circuits in residential and infrastructure panels against overload and short-circuit faults up to 400 V AC single-phase or 440 V AC multi-phase. The C-curve (5–10× In) is the standard choice for general-purpose loads like lighting, receptacles, and small motor circuits where inrush is moderate.
Panel fit and DIN-rail integration
Occupies 1 modular width unit (18 mm) on a standard DIN rail. Installation depth is 70 mm; overall depth including terminals is 76 mm. Mounting position is unrestricted, and the IP20 rating with connected conductors means it is intended for enclosed panel use, not washdown environments. Sealable per the evidence, which allows tamper-proofing in metered or secured installations.
Sourcing and compliance documentation
Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time. The manufacturer provides RoHS, REACH, and CE declarations as standard.
