Product details

Siemens 5SY3032-6KL SENTRON MCB — 32 A, B-Curve, 1P+N

The Siemens 5SY3032-6KL is a SENTRON miniature circuit breaker (MCB) with a 1P+N pole configuration, rated 32 A at 230 V AC and a breaking capacity of 4.5 kA per EN 60898. The B-curve tripping characteristic means it trips between 3 and 5 times rated current — suited for resistive and general-purpose loads where inrush is modest, such as lighting circuits or control transformers in a panel.

Mounting and integration

Snaps onto standard DIN rail (35 mm) and occupies one width unit (18 mm). Mounting position is any, so it fits horizontal or vertical busbar arrangements. Depth is 76 mm with an installation depth of 70 mm behind the panel face — standard for this SENTRON compact series. IP20 protection (with connected conductors) means it is suitable for installation inside a closed panel or enclosure — not for washdown or outdoor exposure.

Frequently asked questions

How do I get current pricing and availability for 5SY3032-6KL?

Submit an RFQ through this listing; availability and current pricing are confirmed at quote time.

Will 5SY3032-6KL drop into a panel that was specified around 5SY6040-6 without rewiring?

Yes — both share the same 18 mm width, 76 mm depth, DIN-rail mount, and 1P+N pole configuration, so physical fit is identical. The difference is rating: 5SY6040-6 is a 40 A B-curve MCB with 6 kA breaking capacity, while the 5SY3032-6KL is 32 A / 4.5 kA. No rewiring needed for the same footprint.
