Breaking capacity is 15 kA per EN 60898 and 25 kA per IEC 60947-2, with a DC rating of 15 kA per IEC 60947-2. ## Breaking capacity and standard compliance The 15 kA rating under EN 60898 covers the standard household/commercial installation curve; the 25 kA under IEC 60947-2 is the industrial rating, meaning this breaker can interrupt fault currents up to 25 kA at 400 V AC without welding its contacts or cascading failure upstream. The DC rating of 15 kA per IEC 60947-2 covers DC-side faults in rectified supplies or battery banks. UL 1077 and CSA C22.2 No. 235 recognition at 5 kA confirms suitability for North American supplementary protection applications. Snap-on mounting to DIN rail, any orientation. The 4 MW width (72 mm) means it occupies four 18 mm slots — plan your rail fill accordingly. Vibration resistance per IEC 60068-2-6: ±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz — suitable for machine-mounted panels. ## Environmental and compliance documentation Halogen-free and silicon-free construction, sealable for tamper-proofing. Ambient temperature range -40 °C to 75 °C, with humidity derating: max 95% RH at 55 °C, tapering to 35% RH at 75 °C.","metaTitle":"Siemens 5SY7625-8 SENTRON MCB, 25A 4P D-Curve, 15/25kA","metaDescription":"Siemens 5SY7625-8 SENTRON miniature circuit breaker, 25 A, 4-pole (3P+N), D tripping characteristic, 15 kA (EN 60898) / 25 kA (IEC 60947-2) breaking capacity.

The 5SY7625-8 is 25 A with a D-curve. Both share the same 4 MW footprint and SENTRON platform, but the D-curve on the 25 A unit handles higher inrush — swap only if the load's starting current is within the C-curve magnetic trip threshold (5–10× In vs 10–20× In)."},{"question":"Where can I buy 5SY7625-8?","answer":"This part is sourced and quoted to order against an RFQ through independent distribution.
