What this MCB is and what the ratings mean
The Siemens 5SL6010-7 is a SENTRON miniature circuit breaker in a compact 1P+N design — one protected pole plus a switched neutral — with a C-curve trip characteristic rated at 10 A. The C-curve means it trips between 5 and 10 times rated current, so it's sized for moderate inrush loads like small motors, lighting banks, and general-purpose outlets in residential or light commercial panels. The 6 kA breaking capacity (per IEC/EN 60898-1 and GB/T 10963.1) tells you it can safely interrupt a fault current up to 6,000 A at 230 V AC without welding its contacts or cascading damage upstream. That 6 kA rating is the standard domestic and light infrastructure level — adequate for most final sub-circuits where the prospective short-circuit current stays under that threshold.
Panel fit and mounting
Snaps onto standard DIN rail (fastening method per) and occupies a single modular width unit (18 mm wide,). Depth is 76 mm with an installation depth of 70 mm; height is 90 mm. That 18 mm width per pole is the standard 1 MW form factor — no surprises for panel layout or fill factor. Mounting position is unrestricted, which helps when you're squeezing breakers into a tight gland plate area. The IP20 rating applies with connected conductors, so it's fine inside a closed panel but not for wet or washdown environments.
Environmental and compliance details
Rated for ambient temperatures from -40 °C to 75 °C, which covers unheated utility rooms and outdoor enclosures in most climates. Halogen-free and silicon-free construction — relevant if the panel sits in a clean room or a corrosive environment where outgassing matters. Pollution degree 2 and overvoltage category III are the usual residential and light industrial levels. Vibration resistance per IEC 60068-2-6 is verified, so it holds up on a machine frame or near a transformer. The breaker is sealable — you can lock the toggle position to prevent tampering on a critical circuit.
