Product details

The 10 kA breaking capacity (rated both per EN 60898 and IEC 60947-2) tells you it can safely interrupt a fault current up to 10,000 A at 400 V AC without welding its contacts or cascading failure upstream. That 10 kA rating is the same under both standards, so you don't need to derate when switching between residential (EN 60898) and industrial (IEC 60947-2) applications.

Panel integration and deployment

It accepts auxiliary switches, shunt trips, and other add-on devices via the product extension interface, so you can add remote signaling or emergency trip without replacing the breaker.

Frequently asked questions

How do I get current pricing and availability for 5SL4101-8?

Pricing and availability are confirmed at quote time. Submit an RFQ through this listing; the part is sourced and quoted to order through independent distribution channels.

Will 5SL4101-8 drop into a panel that was specified around 5SL6120-7 without rewiring?

Yes, the 5SL4101-8 shares the same 18 mm width, 76 mm depth, and DIN-rail mounting as the 5SL6120-7, so it fits the same physical footprint and wiring. However, the 5SL4101-8 uses a D tripping characteristic (versus C on the 5SL6120-7) and a 1 A rating, so you must verify that the protection coordination and load current are compatible with the change.

What is 5SL4101-8's listed depth (76 mm) on this component line?

The 5SL4101-8 has a depth of 76 mm, with an installation depth of 70 mm. This matches the standard SENTRON 5SL series depth, so it fits existing panel layouts designed for that family.

What is 5SL4101-8's listed width (18 mm) on this component line?

The 5SL4101-8 has a width of 18 mm, which is one modular unit on a DIN rail. This is the same width as the 5SL6120-7 and other single-pole SENTRON breakers.
