Product details

Siemens 5SY7506-7 — SENTRON MCB, C-Curve, 2-Pole

It carries a 15 kA breaking capacity per EN 60898 and 40 kA per IEC 60947-2, so it handles high prospective fault currents common in industrial panel feeds — the 40 kA figure is the one that matters for SCCR coordination downstream of a transformer or large motor branch. Rated for 230 V AC (single-phase) and up to 60 V DC, with neutral conductor switching built in.

Any mounting position, IP20 with conductors connected. Sealable, halogen-free, silicon-free. Combined terminals top and bottom, supply cord position any — no orientation restrictions inside the panel.

Current production — no phase-out or last-time-buy announced.

Frequently asked questions

What are the key breaking capacity ratings for 5SY7506-7?

15 kA per EN 60898 at 230 V AC, 40 kA per IEC 60947-2 at 230 V AC, and 15 kA at DC per IEC 60947-2. For UL 1077 / CSA C22.2 No.235 applications the rating is 5 kA.

What compliance documentation does this brand provide for 5SY7506-7?

The breaker is certified to IEC / EN 60898-1, IEC / EN 60947-2, and UL 1077. It is halogen-free and silicon-free. Specific RoHS/REACH declarations are available from the manufacturer.

Will 5SY7506-7 drop into a panel that was specified around 5SY4140-7 without rewiring?

Both are 2-pole 1P+N SENTRON MCBs with the same 36 mm width and DIN-rail mounting, so physical fit is the same. The 5SY7506-7 carries higher breaking capacity (40 kA vs the 5SY4140-7's typical 10 kA), so it can replace it directly as long as the C-curve and voltage ratings match the branch circuit.
