What this MCB is and what the ratings mean
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 C-curve means it trips between 5 and 10 times rated current — designed for inductive loads like small motors, pumps, and lighting banks where inrush is moderate. 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
Snaps onto standard 35 mm DIN rail (EN 60715) in any mounting position — no orientation restrictions. 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. IP20 with connected conductors means it's protected against solid objects larger than 12 mm but not against moisture — standard for dry indoor distribution boards. Rated for overvoltage category III and pollution degree 2, so it's suited for fixed-installation sub-distribution in residential and infrastructure buildings, not for outdoor or wet locations.
