The quick-assembly fastening and any mounting position simplify panel integration. DIN-rail mount, 36 mm wide (2 MW), depth 76 mm with 70 mm installation depth. Sealable with a lead seal for metering or tamper-proof applications. Vibration resistance per IEC 60068-2-6 covers ±1 mm at 5–25 Hz and 50 m/s² at 25–150 Hz — typical for machine-mounted panels. Approvals include IEC/EN 60898-1, IEC/EN 60947-2, and UL 1077 / CSA C22.2 No. 235. The UL 1077 supplementary-protector rating is 5 kA — check that your fault-current study stays under that threshold if the installation requires UL listing.","metaTitle":"Siemens 5SY7250-8 SENTRON MCB 2P D-curve 15 kA, 400 VAC","metaDescription":"Siemens 5SY7250-8 SENTRON miniature circuit breaker, 2-pole D-curve, 15 kA breaking capacity per IEC/EN 60898-1 and IEC 60947-2.
