Siemens 5SL4132-6CC — SENTRON 1-pole MCB, B-curve, 32 A
The Siemens 5SL4132-6CC is a SENTRON miniature circuit breaker (MCB) from the 5SL4CC design family, built for residential and infrastructure branch-circuit protection. It is a single-pole unit rated 32 A at 400 V AC with a B tripping curve, meaning it trips instantaneously at 3–5× rated current — the standard choice for resistive and general-purpose loads where nuisance tripping from inrush is not expected.
Breaking capacity and voltage ratings
Breaking capacity is 10 kA per EN 60898, which covers most residential and light commercial panel fault levels. Single-phase operation is rated 250 V AC; multi-phase operation goes to 440 V AC. DC rating is 60 V maximum, so this is an AC-primary device — not for DC subpanels unless the voltage is well under that ceiling.
DIN-rail footprint and panel fit
Occupies one width unit (18 mm) on a DIN rail, with a depth of 76 mm and an installation depth of 70 mm. Mounting position is any orientation, which simplifies layout in crowded enclosures. Terminal capacity accepts 0.75 mm² to 25 mm² — solid or stranded — and the housing is sealable, halogen-free, and silicon-free.
