The Siemens SENTRON 5SL6132-6RC is a 1-pole miniature circuit breaker rated 32 A at AC with a B tripping characteristic and 7.5 kA breaking capacity per EN 60898. It snaps onto a standard DIN rail in a single modular width (18 mm), so it fits tight panel layouts without crowding adjacent devices. Rated for 415 V AC supply voltage (250 V single-phase), it handles residential and light-commercial branch circuits where the B curve provides fast magnetic trip on moderate inrush — think lighting, general-purpose receptacles, and small resistive loads.
What the ratings mean for fit
The 7.5 kA breaking capacity at 415 V AC per EN 60898 tells you it can safely interrupt a fault current up to that level without welding contacts or cascading failure upstream. That matches typical domestic and small-commercial service-entrance ratings; if your available fault current exceeds 7.5 kA, step up to the 10 kA variant in the same SENTRON family. B-curve trip: magnetic release between 3× and 5× In (96–160 A for this 32 A unit). That's faster than a C curve on moderate surges, so it's a good fit for circuits without heavy motor or transformer inrush — keeps nuisance trips off the line. IP20 with connected conductors means it's protected against finger contact but not against water ingress. Fine inside a closed panel; not for washdown or outdoor exposure without a secondary enclosure. Rated for ambient temperatures from -40 °C to 75 °C, so it can live in unconditioned enclosures or outdoor cabinets in cold climates — no derate worry at the panel's internal temperature.
