Product details

The Siemens SENTRON 5SL3104-7 is a 1-pole miniature circuit breaker rated 4 A with a C tripping characteristic, designed for AC circuits up to 400 V (single-phase 250 V). It breaks 4.5 kA per EN 60898 and 5 kA per IEC 60947-2 — the EN figure governs residential and commercial distribution panels; the IEC figure applies when the breaker is used in industrial motor-control or branch circuits where the prospective fault current is higher.

Mounting position is unrestricted, which simplifies layout in tight enclosures.

Frequently asked questions

Where can I buy 5SL3104-7 and how do I get a price?

The 5SL3104-7 is sourced to order against an RFQ through independent distribution. Submit a request for a firm price and availability quote — current pricing and stock position are confirmed at quote time.

What is 5SL3104-7's listed depth (76 mm) on this component line?

The 5SL3104-7 has a depth of 76 mm and an installation depth of 70 mm, which fits standard DIN-rail enclosures with adequate wiring space behind the breaker.

What is 5SL3104-7's listed width (18 mm) on this component line?

The 5SL3104-7 is 18 mm wide — exactly 1 modular width unit — so it occupies one pole position on a DIN-rail busbar.

Will 5SL3104-7 drop into a panel that was specified around 5SL4363-7 without rewiring?

No — the 5SL4363-7 is a 3-pole breaker (54 mm wide, 3 MWU) rated 63 A with 10 kA breaking capacity. The 5SL3104-7 is a single-pole 4 A unit. They share the same depth (76 mm) and height (90 mm), but the pole count, current rating, and busbar spacing are different; a panel designed for the 5SL4363-7 would need rewiring and a different busbar to accept the 5SL3104-7.
