That dual breaking capacity means it meets both residential-standard (EN 60898-1) and industrial-standard (IEC 60947-2) requirements, so the same part can serve a panel that needs UL 1077 listing (5 kA per that standard) or a European industrial installation that demands the higher 20 kA SCCR. If your load has a high inrush that exceeds a B-curve but doesn't need the D-curve's wider tolerance, this is the right characteristic. At 400 V, the 20 kA figure (IEC 60947-2) covers most industrial distribution panels; the 10 kA (EN 60898-1) is sufficient for final subcircuits. The DC rating of 15 kA at 60 V means it also works in DC bus applications up to that voltage — useful in battery-backed or solar-combiner panels. The quick-assembly system means it clips onto the rail without tools and can be removed with a screwdriver lever. Mounting position any — no derating needed for horizontal or inverted orientation. Sealable — the toggle can be locked in the off position with a padlock, which satisfies lockout/tagout requirements without an accessory.","metaTitle":"Siemens 5SY4225-7 SENTRON MCB, 2P C-curve, 10/20 kA, 400 VAC","metaDescription":"Siemens 5SY4225-7 SENTRON miniature circuit breaker, 2-pole, C characteristic, 10 kA per EN 60898-1 / 20 kA per IEC 60947-2.
