Product details

Integrator note — 5SY7525-7

The 1P+N configuration switches the neutral, which is required in some regional codes (UK, parts of Europe) and simplifies panel wiring when a shared neutral bar isn't available.

The 5SY7525-7 carries three breaking-capacity ratings depending on the standard applied: 15 kA at 230 V AC per EN 60898, 25 kA at 230 V AC per IEC 60947-2, and 5 kA at 250 V AC per UL 1077 / CSA C22.2 No.235. The UL 1077 rating (5 kA) confirms it is recognized as a supplementary protector for North American panels, not a branch-circuit device.

Ambient range -40 °C to 75 °C, with humidity derating above 55 °C (max 95% RH at 55 °C, dropping to 35% at 75 °C). Halogen-free and silicon-free construction, which matters for clean-room or food-processing zones where outgassing can contaminate product.

Compliance documentation

Certified to IEC / EN 60898-1 and IEC / EN 60947-2, with UL 1077 and CSA C22.2 No.235 recognition. The manufacturer provides standard CE declaration of conformity and RoHS/REACH material declarations on request — these are typically available as a PDF download from the Siemens Industry Online Support portal.

Frequently asked questions

Where can I buy 5SY7525-7 and get a price?

The 5SY7525-7 is sourced to order through independent distribution. Submit an RFQ and we will confirm availability and current pricing at quote time.

Will 5SY7525-7 drop into a panel specified around 5SY4116-7CV without rewiring?

Both are 2-pole SENTRON MCBs on a 36 mm DIN-rail footprint, so the physical swap is straightforward. The key difference is the tripping characteristic: 5SY7525-7 is a C-curve (5–10× In), while the 5SY4116-7CV is a B-curve (3–5× In). If the original design relied on B-curve selectivity for low-inrush loads (resistive heaters, control transformers), a C-curve may delay tripping on a minor overload. Verify the load type and coordination study before substituting.

What compliance documentation does Siemens provide for 5SY7525-7?

The 5SY7525-7 carries CE marking under IEC / EN 60898-1 and IEC / EN 60947-2, plus UL 1077 and CSA C22.2 No.235 recognition. RoHS and REACH declarations are available from the manufacturer on request.
