Mounts on DIN rail or with screw fixing in any orientation. At 4.5 modular width units (81 mm wide, 76 mm deep, 90 mm tall) it fits standard SENTRON distribution boards and sub-distribution panels. Sealable design allows lockout/tagout compliance on critical circuits. Vibration resistance per IEC 60068-2-6 and shock resistance per IEC 60068-2-27 — suitable for industrial panels on conveyors, pumps, or machine tools where mechanical stress is a factor.","metaTitle":"Siemens 5SP4392-7 SENTRON MCB, 3P C 125A, 10kA, 400V","metaDescription":"Siemens 5SP4392-7 SENTRON miniature circuit breaker, 3-pole, C-curve, 125 A, 10 kA breaking capacity at 400 V AC.
