Product details

The Siemens SENTRON 5SP4480-6 is a 4-pole miniature circuit breaker with a B tripping characteristic, rated at 80 A and 10 kA breaking capacity according to EN 60898 at 400 V AC. Rated for 50/60 Hz supply and 400/440 V AC, it handles the standard European three-phase panel voltage.

Snaps onto DIN rail or screws directly to the panel backplate — both fastening methods are supported. Mounts in any position, which simplifies layout in crowded enclosures. The IP20 rating applies with connected conductors; IP40 at the handle area when a distribution cover is fitted — fine for enclosed panels, not for open washdown areas.

Frequently asked questions

How do I get current pricing and availability for 5SP4480-6?

Submit an RFQ through this listing. Pricing and stock are confirmed at quote time; we source through independent distribution and quote to order.

What compliance documentation does this brand provide for 5SP4480-6 (RoHS, REACH, UL, IEC)?

The breaker is designed to EN 60898 (the 10 kA rating is per that standard), carries an overvoltage category 3 and pollution degree 3 rating, and is halogen-free and silicon-free. RoHS/REACH declarations are standard for Siemens SENTRON products; request them with the RFQ.

Will 5SP4480-6 drop into a panel that was specified around 5SL4363-7 without rewiring?

Both are 4-pole B-curve MCBs on DIN rail, but the 5SP4480-6 is rated 80 A with 10 kA breaking capacity, while the 5SL4363-7 is a different current rating and breaking capacity — check the panel's coordination study before swapping. The physical footprint (6 MW, 108 mm wide) is the same, so it fits the same DIN-rail slot.
