Product details

The Siemens SENTRON 5SL4101-6 is a 1-pole miniature circuit breaker with a B tripping characteristic, rated 1 A at 230/400 V AC. The 18 mm width (1 modular unit) fits standard DIN-rail enclosures; the 76 mm depth leaves clearance for wiring and busbar connections in a panel.

Ratings and fit

At 1 A, this breaker protects a 230 V single-phase circuit drawing up to 230 VA, or a 400 V three-phase line drawing roughly 690 VA. The 10 kA breaking capacity (per both EN 60898 and IEC 60947-2) means it can safely interrupt a fault current up to 10,000 A without welding contacts or cascading upstream.

Panel integration

Sealable terminals allow tamper-proofing after commissioning.

Frequently asked questions

What is the breaking capacity of the 5SL4101-6?

10 kA per EN 60898 and IEC 60947-2 at 400 V AC. That is the same rating for both standards, so it covers residential and industrial branch-circuit fault levels.

What is the difference between the 5SL4101-6 and the 5SL4363-7?

The 5SL4363-7 is a 3-pole, C-curve 63 A breaker — different pole count, characteristic, and current rating. It will not drop into a panel wired for the 1-pole 5SL4101-6 without rewiring and a wider 54 mm (3 MW) footprint.

Where can I buy the 5SL4101-6?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
