Product details

The Siemens 5SP4291-7 is a SENTRON 5SP series miniature circuit breaker (MCB) rated 100 A, C-curve, 2-pole, with a 10 kA breaking capacity per EN 60898 at 400 V AC. This is the part you spec when a 100 A branch needs Type C magnetic trip (5–10x In) for moderate inrush — motor starters, transformer primaries, capacitor banks.

Snaps onto DIN rail or screw-fixes; mounting position is unrestricted. IP20 with connected conductors, IP40 at the handle with a distribution cover; fine for enclosed distribution boards but not for washdown zones.

Frequently asked questions

Where can I buy 5SP4291-7 and how do I get a price?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing confirmed at quote time — submit an RFQ for a firm number.

Will 5SP4291-7 drop into a panel that was specified around 5SP4292-7 without rewiring?

The 5SP4291-7 and 5SP4292-7 share the same SENTRON 5SP platform — same DIN-rail footprint, same 54 mm width (3 MW), same 70 mm installation depth. The difference is the trip curve: 5SP4291-7 is C-curve (5–10x In), while 5SP4292-7 is D-curve (10–20x In). Mechanically interchangeable; no rewiring needed if the existing wiring and busbar are rated for 100 A.

What is 5SP4291-7's listed depth (76 mm) on this component line?

The overall depth is 76 mm; the installation depth (behind the panel face) is 70 mm.

What compliance documentation does this brand provide for 5SP4291-7?

The 5SP4291-7 carries EN 60898 rating for breaking capacity. It is halogen-free and silicon-free. For specific compliance certificates (CE, UKCA, EAC, UL), refer to Siemens documentation for the SENTRON 5SP series.
