The dual breaking capacity rating means it's certified for both the residential standard (EN 60898, 10 kA) and the industrial standard (IEC 60947-2, 15 kA) — the higher figure governs when the MCB is applied in an industrial panel under the IEC 60947-2 scope. Rated insulation voltage 440 V AC, pollution degree 3, overvoltage category III — all standard for a distribution board in a factory or commercial building. ## Panel integration and environment Snaps onto standard mounting rail, 18 mm wide, 70 mm deep — fits into any 1-module slot in a consumer unit or sub-distribution board. Combined tunnel terminals top and bottom accept copper conductors; tighten to 3.5 Nm. IP20 with connected conductors, IP40 in the handle range — fine for enclosed panels; not for wet washdown areas. Vibration tested to 50 m/s² at 25–150 Hz and 60 m/s² at 35 Hz for 4 seconds — survives shipping and moderate machine vibration. Sealable for tamper-proof applications.","metaTitle":"Siemens 5SJ4106-8HG40 SENTRON MCB, 1P, D Curve, 10 kA","metaDescription":"Siemens 5SJ4106-8HG40 SENTRON miniature circuit breaker, 1-pole, D tripping characteristic, 10 kA per EN 60898, 15 kA per IEC 60947-2.
