The Siemens SENTRON 5SL6132-7RC is a 1-pole miniature circuit breaker rated 32 A with a C tripping characteristic and 7.5 kA breaking capacity according to EN 60898. The 7.5 kA SCCR at 415 V AC tells you it can safely interrupt a bolted fault up to that level without welding its contacts or cascading upstream; that's the standard residential and light-commercial building protection level per EN 60898. Single-pole construction (1 MW width at 18 mm) means it protects one phase leg — use it in single-phase branch circuits or as a phase-specific breaker in multi-pole assemblies.
Where it fits and how it mounts
At 18 mm width (1 modular unit) and 76 mm depth, it leaves generous finger space in a crowded enclosure; the 70 mm installation depth is the rail-to-front-panel clearance needed.
