What it is and where it fits
The Siemens 5SL6032-6 is a SENTRON miniature circuit breaker (MCB) in a compact 1P+N design — it switches both the phase and the neutral, with the neutral pole following the phase. It is a B-curve device with 6 kA breaking capacity at 230 V AC per IEC/EN 60898-1. The 18 mm width (one modular unit) and DIN-rail fastening mean it snaps into any standard distribution board or sub-panel without eating extra space. Mounting position is unrestricted, and the IP20 rating with connected conductors is typical for enclosed panel use — no special sealing needed inside a cabinet.
What the ratings mean for the panel builder
The 76 mm depth and 70 mm installation depth are key for shallow enclosures. The 18 mm width per pole (1 MWU) allows high rail density. The B-curve characteristic means the magnetic trip threshold is lower than a C-curve, so it's more sensitive to short-circuit faults but may nuisance-trip on motor or transformer inrush. That's by design for the intended residential/infrastructure duty. The neutral conductor is switched (1P+N), which is required in some national wiring regulations for single-phase final circuits — verify your local code. Operating temperature range of -25 °C to 45 °C at up to 85% relative humidity, derating to 43% rF above 45 °C up to 60 °C. That covers most indoor panel environments; if the breaker lives in an unconditioned outdoor cabinet in a hot climate, check the derating curve for the actual ambient. Power loss is 2.8 W per pole at rated current in hot operating state — negligible for thermal budgeting in a populated board, but worth noting if you're packing high-density MCBs in a sealed enclosure with no forced ventilation.
Compliance and documentation
Designed and tested to IEC/EN 60898-1 and GB/T 10963.1 (Chinese national standard). Overvoltage category III, pollution degree 2 — standard for fixed-installation distribution boards. The product is halogen-free and silicon-free, which matters for environments where outgassing from a fault could contaminate sensitive equipment or where silicone contamination affects downstream processes. Vibration resistance per IEC 60068-2-6 is confirmed, and the mechanical service life is rated at 10,000 operating cycles typical. Sealable design allows the installer to lock the toggle position — useful for tamper-proofing in public-access panels.
