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.","metaTitle":"Siemens 5SY7525-7 SENTRON MCB, 2P C-Curve, 15/25 kA","metaDescription":"Siemens 5SY7525-7 SENTRON miniature circuit breaker, 2-pole 1P+N, C-trip characteristic, 15 kA (EN 60898) / 25 kA (IEC 60947-2).

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."},{"question":"What compliance documentation does Siemens provide for 5SY7525-7?","answer":"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.
