The Siemens 5SL6532-6 is a SENTRON miniature circuit breaker — 1P+N pole configuration, B tripping characteristic, rated 32 A at 230 V AC. It breaks fault currents up to 6 kA per both EN 60898 and IEC 60947-2, so it handles the standard residential and light commercial short-circuit duty without needing an upstream fuse. Rated for ambient temps from -40 °C to 75 °C, overvoltage category III, pollution degree 2 — typical for a distribution board environment.
Sealable with a lead or wire seal — useful for utility or rental-metering applications where tamper evidence is required. Halogen-free and silicon-free construction, so it won't outgas corrosive compounds in enclosed or sensitive environments. IP20 with connected conductors; fine for a dry indoor distribution board, not for washdown.
