Product details

The Siemens 5SL3114-7 is a SENTRON miniature circuit breaker (MCB) — a 1-pole, C-curve unit rated 0.3 A at 230/400 V AC. It breaks 4.5 kA per EN 60898 and 5 kA per IEC 60947-2, so it covers residential and light-commercial branch circuits where the available fault current stays under that level.

Mounting position is unrestricted — horizontal, vertical, or flat — which simplifies panel layout when the distribution board is tight on space.

The 5SL3114-7 carries a current-production lifecycle status.

Frequently asked questions

What is the breaking capacity of 5SL3114-7?

4.5 kA per EN 60898 and 5 kA per IEC 60947-2 at 400 V AC.

Where can I buy the 5SL3114-7?

It is available to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time.

Will 5SL3114-7 drop into a panel specified around 5SL4363-7?

No — the 5SL4363-7 is a 3-pole unit occupying three modular widths (54 mm), while the 5SL3114-7 is a single-pole unit in 18 mm. They share the same depth (76 mm) and mounting position flexibility, but the pole count and width are different, so direct swap without rewiring is not possible.
