It handles 60 V DC as well. The 10 kA rating under EN 60898 is the standard for domestic/commercial distribution boards; the 15 kA under IEC 60947-2 is the industrial equivalent, giving you headroom for higher fault currents in plant-floor panels. The D-curve trips magnetically at 10-20x In, so it ignores the brief current spike of a motor start or a capacitor bank charge. At 18 mm wide, it fills one slot on a DIN-rail assembly — the same footprint as any standard 1-pole MCB, so it drops into an existing panel without re-spacing. The 70 mm depth matches the typical SENTRON profile, so it aligns with neighboring devices on the rail. It's sealable (lockable with a padlock or seal cap) — useful for isolating a circuit during maintenance and proving it's locked out.","metaTitle":"Siemens 5SJ4114-8HG41 SENTRON MCB, 1P, D-curve, 10 kA","metaDescription":"Siemens 5SJ4114-8HG41 SENTRON miniature circuit breaker, 1-pole, D tripping characteristic, 10 kA per EN 60898, 15 kA per IEC 60947-2.
